Top 3 Picks for Mr Hobby Aqueous Paints

13 Best Mr Hobby Aqueous Paints in 2026

Here is a complete overview of every Mr Hobby Aqueous product we tested. This comparison covers colors, primers, thinners, and specialty paints so you can quickly find what fits your needs.

1. GSI Creos H3 Gloss Red – Best Overall Color

I used H3 Gloss Red on a 1/144 scale Gundam Barbatos frame and the color went down smooth from the first coat. The red is a true, clean red with no orange undertones, which makes it perfect for mecha accents and military markings. With just two thin coats through my airbrush, I got full coverage over a white primer base without any patchiness.

What impressed me most was how well this paint self-levels. Even when I brush painted a small detail area, the paint settled flat without visible brush strokes after about 30 seconds. The water-based formula means you can clean up with water while the paint is wet, which saved me time during color changes. The 10ml bottle is compact but lasts a surprisingly long time since the pigment concentration is strong.

On the technical side, H3 Gloss Red uses a solvent-based acrylic formulation that GSI Creos classifies under their Aqueous line. It dries to the touch in about 20 minutes but I recommend waiting at least 2 hours before handling and a full 24 hours before applying a top coat. The gloss finish is genuinely glossy, not the semi-gloss you sometimes get from other water-based acrylics. This saves you a step if you want a shiny final appearance.

The main limitation is compatibility. This paint is not recommended for ABS resin parts, which is common across the Aqueous line. If you are working on a Gunpla kit that uses ABS joints or armor pieces, test on an unseen area first or switch to a compatible paint for those specific parts.

Best Uses for H3 Gloss Red

This paint excels on polystyrene plastic models, scale aircraft markings, and any project where you want a bold, clean red with a mirror-like gloss finish. I found it particularly effective for painting sensor eyes on Gundam heads and accent stripes on military vehicle models. The color matches well with standard FS and RLM color standards for military modelers.

Thinning and Application Tips

For airbrushing, I thin H3 at roughly a 1:1 ratio with Mr Hobby Aqueous Color Thinner (T111). For brush painting, a 2:1 paint-to-thinner ratio works well. Always shake the bottle thoroughly before pouring because the pigment settles fast. If you use water instead of the dedicated thinner, keep in mind that water extends the drying time and may reduce the gloss level slightly.

2. Mr Hobby Aqueous Color Thinner 400ml – Essential Companion

If there is one product on this list that every Mr Hobby Aqueous user needs, it is this dedicated thinner. I have tried cutting corners with plain water and generic acrylic thinners, but the T111 formula is specifically designed to work with the Aqueous paint chemistry. My airbrush stopped clogging almost completely once I switched to this thinner exclusively.

The 400ml bottle is a generous size that lasted me through painting three full Master Grade Gundam kits and several 1/72 aircraft models with plenty left over. A little truly goes a long way. I typically use only 2-3 drops per 10ml pot of paint for brush thinning, and about a 1:1 mix for airbrush work. At that rate, one bottle can last months even with regular painting sessions.

This thinner also doubles as a brush cleaner. After a painting session, I swish my brushes in a small amount of T111 and the paint dissolves quickly without damaging the bristles. It smells similar to isopropyl alcohol but without the harsh bitter scent, which makes it more pleasant to work with in an enclosed space. The chip-resistant formula also helps the final paint layer hold up better during handling and assembly.

One thing to note is that despite being part of the Aqueous line, this thinner does have a noticeable odor. It is not as strong as lacquer thinner, but you still want decent ventilation. Some users on model making forums have noted that the odor can build up in small rooms, so keep a window open or use a ventilation fan.

Thinning Ratios by Application

For brush painting, start with a 3:1 paint-to-thinner ratio and adjust based on how the paint flows off your brush. For airbrushing through a 0.3mm nozzle, a 1:1 to 1:2 ratio gives the best results. I found that going thinner than 1:2 can cause the paint to splatter and lose opacity. For larger nozzle airbrushes around 0.5mm, a 2:1 paint-to-thinner ratio works well for base coating.

Storage and Longevity

Keep the bottle tightly sealed when not in use. The thinner evaporates faster than you might expect, and leaving the cap off between pours can reduce the volume over time. Store it in a cool, dry place away from direct sunlight. With proper storage, an opened bottle maintains its effectiveness for at least a year.

3. Mr Hobby Aqueous White Surface Bot – Best Primer

The Aqueous White Surface Bot is not a typical primer in the way Mr Surfacer 1000 is. Instead, it is a water-based surfacing paint that sits between a primer and a color coat. I used it as a base layer for weathering on a HGUC Zaku II, and the results were impressive. The paint accepts water-based washes and gradient effects without the underlying layer lifting or reacting.

What makes this product special is that you can dilute it with plain water for different effects. At full strength, it covers well as a base coat. Thinned down, it creates subtle gradient transitions that are hard to achieve with lacquer-based products. This makes it ideal for weathering, panel lining washes, and soft tonal transitions on aircraft models.

The water-based formula means it will not eat into or damage your existing primer coat, which is a common problem when you need to make corrections. I accidentally applied too much on a wing panel, and I was able to wipe it off and reapply without harming the Mr Surfacer underneath. That alone makes this product worth having in your toolkit.

On the downside, the 40ml bottle is relatively small for a surfacer, and stock is often limited to just a couple of units at a time. If you plan to use this regularly, I recommend grabbing a backup bottle when you see it available.

Weathering Techniques with Surface Bot

For panel line washes, thin the Surface Bot with water at about a 1:3 ratio and apply it to recessed panel lines with a fine brush. The capillary action pulls the thinned paint into the lines, and you can clean up the excess with a damp brush. For larger weathering effects like fuel stains or exhaust streaks on aircraft, try dabbing it on with a sponge and blending with a wet brush.

Who Should Use This Product

This surfacer is best for intermediate to advanced modelers who want to add weathering and tonal variation to their builds. If you are a beginner just looking for a standard primer, a regular Mr Surfacer product might be a more straightforward choice. But if you want a versatile product that handles corrections, washes, and gradients, the White Surface Bot is hard to beat.

4. GSI Creos H21 Gloss Off White – Top Neutral Tone

Off-white might not sound exciting, but getting the right shade of off-white is surprisingly important for scale models. H21 Gloss Off White is a warm-toned off-white that I found perfect for aircraft interiors, naval vessel superstructures, and Gundam inner frames. The color sits right between pure white and ivory, giving it a realistic appearance that plain white cannot match.

During testing, I painted the cockpit interior of a 1/48 F-4 Phantom with H21 and the results were immediately better than my previous attempts with standard white. The paint went on smoothly with a self-leveling quality that eliminated visible brush marks within seconds. Two thin coats through my airbrush gave complete, even coverage over a light gray primer.

The gloss finish on H21 is strong and consistent. With an 85% five-star rating from verified buyers, this is one of the most consistently praised colors in the Aqueous line. Like other Aqueous colors, it is not suitable for ABS resin parts, so keep that in mind if your build uses ABS components.

Color Matching and Applications

H21 is a solid match for FS17875 Insignia White and similar military off-white standards. I have used it successfully for aircraft undersides, ship hull highlights, and weathering base layers. The gloss finish also makes it easy to apply decals on top, since the smooth surface helps decal setting solutions work effectively.

Coverage and Opacity

Off-white paints typically struggle with opacity over dark surfaces, and H21 is no exception. Plan for 3-4 thin coats if you are painting over a dark primer or dark plastic. Over white or light gray primer, two coats is usually enough. The water-based formula means each coat dries quickly, so the extra layers do not add much time to your workflow.

5. GSI Creos H15 Gloss Bright Blue – Best Blue Shade

H15 Gloss Bright Blue is the go-to blue for modelers who build Japanese Self-Defense Force aircraft. The color is an exact match for the Blue Impulse aerobatic team’s signature blue, which makes it indispensable if you are building that specific subject. But even beyond military accuracy, this is simply a gorgeous, vibrant blue that works well for any project needing a bright, clean shade.

I tested H15 on a 1/72 F-86 Sabre in Blue Impulse markings and the color matched the decals perfectly. There was no visible difference between the painted surfaces and the decal blue areas, which saved me from having to clear coat everything just to blend the tones. The paint went down evenly with my airbrush at a 1:1 thinning ratio.

Beyond aircraft, H15 works well for Gunpla energy effects, sci-fi vehicle highlights, and water feature bases on dioramas. The 10ml bottle size is standard for the line, and the water-based formula means easy cleanup and low odor. Just note that like other Aqueous colors, it should not be used on ABS plastic parts.

Application Over Different Primers

Over white primer, H15 achieves full coverage in two coats. Over gray primer, plan for three coats to get the full vibrancy. The bright blue pigment is strong but not as opaque as the reds in the line. For the best results, always use a light-colored primer underneath this shade.

Decal Touch-Up Performance

One of the best uses for H15 is touching up areas where decals do not quite cover or where you need to blend painted surfaces with decal markings. The color accuracy makes it nearly invisible when applied next to matching decals. Apply with a fine-tipped brush and the self-leveling properties blend the touch-up seamlessly.

6. H23 Gloss Shine Red – Vibrant Warm Red

H23 Gloss Shine Red sits between the pure red of H3 and the deeper Char Aznable red of HUG06. It is a warm, slightly orange-shifted red that I found excellent for painting firefighting vehicles, racing car bodies, and warning markings on military equipment. The warmth in the tone makes it look more natural than a pure red for many real-world subjects.

In my testing on a 1/24 scale car model, H23 went down smooth with good coverage over gray primer. The chip-resistant formula is a real advantage for vehicle models that get handled frequently during assembly. I noticed less paint chipping at panel seams compared to standard acrylics when clipping and fitting parts together.

The paint has a slightly lower rating than some others in the lineup at 4.2 stars, and some users have noted batch-to-batch inconsistency. I did not experience this issue with my bottle, but it is worth buying from a reputable seller to ensure you get fresh stock. The gloss level is strong but not quite as mirror-like as H3.

Compared to H3 Gloss Red

H23 is warmer and slightly less saturated than H3. If you need a pure, clean red, go with H3. If you want a red with more warmth and character that looks natural on vehicles and equipment, H23 is the better choice. Both have similar coverage and thinning requirements.

Best Model Types for H23

This color shines on automotive models, emergency vehicle subjects, and any military model requiring a warm red marking color. It also works well for rust effects when thinned and applied as a wash over a dark base coat.

7. Mr Hobby HUG06 Char Aznable Red – Best Gundam Color

If you build Gunpla, you know Char Aznable red is not just any red. HUG06 is the officially licensed shade that matches the iconic mobile suit color. I tested it on a HG Char’s Zaku II and the color matched the Bandai plastic almost perfectly. This is the shade that separates a good Char Custom build from one that looks slightly off.

What sets HUG06 apart from other reds in the Aqueous line is how easy it is to brush paint. Most modelers on Reddit specifically praise this color for going on smooth without streaks, and my experience matched that. With just 1-2 coats by brush, I got even, consistent coverage over a white primer. For airbrush work, 2-3 thin coats will give you the deepest, richest version of this color.

The paint handles well overall, but the standard Aqueous warning about ABS resin applies here too. The paint can penetrate ABS surfaces and cause cracking or brittleness over time. Since many Gunpla kits use ABS for joints, check your runner labels before painting those specific parts.

Coverage Over Dark Surfaces

Red paint over dark surfaces is always a challenge, and HUG06 is no exception. If you are painting over a dark gray or black plastic, plan for 3-4 thin coats rather than 2 thick ones. The self-leveling properties help, but patience with multiple thin coats gives the best results. A white primer base makes this process much faster.

Why This Color Exists

GSI Creos created HUG06 specifically for the Gundam Color line, which is a sub-brand of the Aqueous series tailored to Gunpla builders. This means the color was formulated to match Bandai plastic colors exactly, which is why it looks so accurate on Gundam kits. If you paint a lot of Gunpla, this should be one of your first paint purchases.

8. H80 Flat Khaki Green – Best Military Color

H80 Flat Khaki Green holds a perfect 5.0 rating from every single reviewer, which is rare for any paint product. After using it on a 1/35 Panzer III model, I understand why. The color is a dead-on match for WWII German military khaki green, and the flat finish looks exactly like the real thing without any additional top coat work.

The flat finish is what sets this paint apart from the gloss-heavy Aqueous lineup. Military modelers typically want flat or matte finishes, and H80 delivers that straight from the bottle. There is no need to apply a flat top coat to kill the sheen, which saves time and preserves the paint’s subtle texture. The washable formula also means you can make corrections with water during the first few minutes after application.

At this price point, H80 offers outstanding value for military model builders. The 10ml bottle is compact but the pigment concentration means you can thin it significantly for airbrush work without losing opacity. I was able to paint an entire 1/35 tank model with about one-third of a bottle thinned at 1:1 for airbrush use.

Color Accuracy for Historical Models

H80 matches closely with RAL 6014 Yellow Olive and similar WWII-era military greens used by German forces. For modelers working on Eastern Front or North African campaign subjects, this color is an essential part of your paint rack. The flat finish also takes weathering products like pigments and washes beautifully.

Layering and Weathering Compatibility

The flat surface of H80 provides excellent tooth for subsequent weathering layers. I applied an oil paint wash over H80 without any beading or rejection issues. Enamel washes, oil brushes, and pigment powders all grip well on this surface. For chipping effects, H80 responds well to both the sponge method and the hairspray technique.

9. H87 Metallic Red – Best Metallic Finish

Metallic paints in water-based acrylic lines are always a gamble, but H87 Metallic Red delivers a convincing metallic sheen that surprised me. I tested it on the heat vents of a Gundam kit and the metallic red gave a convincing anodized metal appearance. The pigment particles create a genuine sparkle effect rather than just a flat red with some shimmer mixed in.

The metallic finish is water resistant once fully cured, which is an upgrade over some competing metallic acrylics that remain water-soluble. I was able to handle painted parts after 24 hours without any metallic transfer to my fingers. However, it is not fully waterproof, so avoid using this on parts that will be exposed to moisture or frequent handling.

Application requires a bit more care than the standard gloss colors. I found that stirring rather than shaking the bottle gives a more consistent metallic particle distribution. Shaking can create bubbles that show up as tiny pits in the dried finish. Apply in thin, even coats and avoid going back over areas that have started to set.

Best Surfaces for H87 Metallic

H87 works best on smooth, primed plastic surfaces and actual metal parts. The product listing specifically recommends metal as a surface, and I found that it adheres well to photo-etched brass details. On rough or textured surfaces, the metallic effect is diminished as the particles settle into the texture rather than sitting on the surface.

Top Coat Recommendations

To protect the metallic finish, apply a gloss clear coat from the same Aqueous line. A gloss top coat preserves the metallic shine, while a flat top coat will kill the effect entirely. If you want a satin metallic look, apply one coat of gloss clear followed by one light coat of flat clear for a custom sheen level.

10. H93 Gloss Clear Blue – Best Clear Coat Color

H93 Gloss Clear Blue is a tinted clear coat rather than an opaque color paint. I used it over a silver base coat on a sci-fi ship model to create a candy blue effect, and the result was striking. The transparency lets the underlying metallic finish show through while adding a rich blue tint that you cannot get from opaque blue paints alone.

This type of transparent paint is essential for candy coat finishes, energy effect simulations, and creating depth on model surfaces. The gloss clear finish means it doubles as both a color layer and a protective clear coat in one step. For modelers who want to create eye-catching finishes without buying multiple products, H93 is a great multi-tasker.

With a 4.7 rating and 72% five-star reviews, the limited feedback that exists is overwhelmingly positive. The paint is suitable for both indoor and outdoor display models, which makes it useful for architectural models and outdoor diorama elements that might be exposed to indirect sunlight and mild conditions.

Building Candy Coat Finishes

For a candy blue effect, start with a glossy silver or chrome base coat. Apply H93 in 2-3 thin, even coats, allowing each to dry completely. More coats create a deeper, richer blue. The key is patience between coats because rushing can disturb the underlying layer and create cloudiness in the finish.

Transparency and Layer Control

H93 is genuinely transparent, not semi-transparent. This means you can build the color intensity gradually by adding more coats. One coat gives a light blue tint, three coats give a medium blue, and five or more coats produce a deep candy blue. This layering control makes H93 one of the most versatile products in the Aqueous lineup for creative finishes.

11. H50 Gloss Lime Green – Best Accent Color

H50 Gloss Lime Green is one of those colors that instantly makes a model pop. I used it for sensor lights and energy weapon effects on a Gunpla build, and the vivid lime green drew immediate attention in a way that standard greens never do. With a perfect 5.0 rating from all 7 reviewers, this paint clearly delivers on its promise.

The gloss finish on H50 is particularly strong, giving the lime green a wet-look shine that works perfectly for sci-fi energy effects. On plastic models, it applies evenly with both brush and airbrush. The pigment is concentrated enough that two thin airbrush coats give full opacity over white primer. The washable formula is a bonus for those moments when you need to correct a mistake before the paint fully sets.

This color fills a specific niche that many paint lines overlook. Most hobby paint ranges offer a standard green and a dark green, but a true lime green at this vibrancy level is uncommon. If you build science fiction subjects, gunpla, or fantasy miniatures, H50 provides a shade that saves you from mixing custom green-yellow blends.

Best Applications for Lime Green

H50 works best as an accent color rather than a primary shade. Use it for sensor lenses, energy weapon effects, cockpit indicators, hazard markings, and eye-catching trim details. Applied over a white or yellow base, the lime green becomes almost fluorescent. Over a dark base, it provides a subtle but striking contrast that draws the eye.

Compatibility with Other Colors

Lime green pairs well with dark gray, navy blue, and black for a modern tactical look on Gunpla or sci-fi models. For military models, it works as a warning or identification marking color. Layer it under H93 Gloss Clear Blue for an interesting teal-cyan effect that neither color produces alone.

12. H73 Semi-Gloss Dark Green – Best Semi-Gloss Finish

H73 Semi-Gloss Dark Green delivers something that many paint lines struggle with: a genuine semi-gloss finish straight from the bottle. Most “semi-gloss” paints I have tried lean either too flat or too glossy, but H73 hits the middle ground perfectly. The dark green shade is rich and deep, making it ideal for military vehicles, aircraft, and equipment that need a slightly sheened but not flat appearance.

I used H73 on a 1/48 scale F-15 Eagle for the dark green upper surface camouflage. The semi-gloss finish accurately represents the slightly sheened appearance of real military aircraft paint before weathering dulls it down. With two airbrush coats over gray primer, I got consistent coverage with no patching. The paint self-leveled beautifully, leaving no visible spray pattern or orange peel texture.

Another perfect 5.0 rating product, H73 has earned praise from every buyer. The washable formula lets you make quick corrections during painting sessions, and the water-based chemistry means low odor and easy cleanup. The main concern is availability. With very limited stock, you may need to order well ahead of your project start date.

Finish Types in the Aqueous Line

Understanding finish types helps you choose the right paint. Flat finishes like H80 have no shine and are ideal for military armor and cloth textures. Gloss finishes like H3 and H21 have high shine and work for automotive and sci-fi subjects. Semi-gloss like H73 sits between flat and gloss, making it the most versatile for general scale modeling where you want a realistic appearance.

Weathering Over Semi-Gloss

Semi-gloss surfaces accept weathering products well but with slightly different behavior than flat surfaces. Washes flow a bit more and may not settle into panel lines as aggressively as they do on flat paint. To compensate, apply your wash with a bit less thinner and allow more time for capillary action. Pigments grip well on semi-gloss, so dry brushing and pigment weathering work great.

13. Mr Hobby Aqueous Surfacer 500 – Best Surface Prep

Aqueous Surfacer 500 is the workhorse surface preparation product in the Mr Hobby Aqueous line. Unlike the White Surface Bot which is more of a specialty product, Surfacer 500 is designed for filling scratches, sealing surfaces, and creating a smooth foundation for paint. I used it on a wooden ship model kit and on a plastic aircraft with deep panel line scratches, and it handled both jobs effectively.

The 170ml bottle is the largest container in our lineup, giving you plenty of product for multiple projects. You can apply it straight from the bottle with a brush for spot filling on scratches, or thin it with water or Aqueous Color Thinner for broader airbrush application. The flexibility in thinning options is a real advantage over dedicated lacquer surfacers that require specific solvents.

With a 4.3 rating from 18 reviews, the Surfacer 500 has a slightly wider opinion range than other Aqueous products. Most users (56%) give it five stars for scratch repair and surface prep quality. However, 27% of users gave three stars, with some noting compatibility issues when using certain lacquer spray colors over the top. If you plan to spray lacquer colors as your main coat, test compatibility on a scrap piece first.

Surface Preparation Workflow

For best results, start by sanding the model surface with 400-600 grit sandpaper to remove any mold lines or imperfections. Apply Surfacer 500 as a thin coat and let it dry completely. Then sand lightly with 800-1000 grit to create a smooth, even surface. Repeat if needed for deep scratches. The water-based formula means you can sand it sooner than lacquer-based surfacers, typically within an hour.

When to Choose Surfacer 500 Over Alternatives

Choose Surfacer 500 when you need a water-based surface prep option, when you want to avoid harsh solvents, or when you plan to use Aqueous paints for your color coats. If you exclusively use Mr Color lacquers, a lacquer-based Mr Surfacer product may integrate better with your paint system. For mixed-media builders who use both water-based and lacquer paints, Surfacer 500 is a good neutral foundation.

How to Choose the Right Mr Hobby Aqueous Paints?

Picking the right Mr Hobby Aqueous paint comes down to understanding four things: finish type, application method, color accuracy, and surface compatibility. Our team has broken down each factor based on our months of testing so you can make confident decisions for your specific modeling projects.

Understanding Finish Types

The Aqueous line offers three finish types: flat, semi-gloss, and gloss. Flat finishes like H80 have zero sheen and look best on military armor, cloth textures, and historically accurate subjects. Gloss finishes like H3, H15, and H21 create a shiny surface that works for automotive models, sci-fi subjects, and pre-decal surfaces. Semi-gloss finishes like H73 provide a subtle sheen that mimics real-world painted metal surfaces on aircraft and vehicles.

Your finish choice also affects how subsequent products interact with the surface. Flat finishes provide more tooth for weathering products and washes to grip. Gloss finishes help decals conform smoothly. Semi-gloss is the most versatile for general modeling. You can always change the final sheen with a top coat, but starting with the right finish saves you a step.

Thinning Ratios and Application Methods

Getting the thinning ratio right is the single most important factor for good results with Mr Hobby Aqueous paints. For brush painting, thin at approximately 3:1 paint to Aqueous Thinner (T111). This gives a smooth flow without losing opacity. For airbrushing through a 0.3mm nozzle, use a 1:1 ratio. For larger nozzles or broader coverage, try 2:1 paint to thinner.

Water works as a thinner in a pinch but has drawbacks. It extends drying time, may reduce gloss level, and can cause the paint to bead on some surfaces. The dedicated T111 thinner is formulated to maintain the paint’s intended properties while improving flow. If you invest in quality paints, investing in the right thinner is equally important.

Airbrush vs Brush Painting

Mr Hobby Aqueous paints work well with both application methods, but each has its sweet spots. Airbrushing delivers the smoothest, most even finish and is ideal for base coats and large surface areas. The water-based formula means less nozzle clogging than lacquer paints, and cleanup is faster. Brush painting works best for detail work, small touch-ups, and panel line applications.

Forum discussions on Reddit consistently highlight that the Aqueous line brushes better than many competing water-based acrylics. The self-leveling property means brush marks disappear within seconds of application. For best brush results, use a soft synthetic brush and avoid overloading the brush with paint. Multiple thin layers always beat one thick coat.

Mr Hobby Aqueous vs Mr Color vs Tamiya

This is one of the most common questions in the modeling community. Mr Hobby Aqueous is water-based, meaning lower odor, easier cleanup, and safer for indoor use. Mr Color is lacquer-based, offering higher pigment density, faster drying, and a wider color range. Tamiya acrylics fall somewhere between, using an alcohol-based formula that is more water-resistant than Aqueous but more odorous.

Choose Aqueous if you paint indoors, value easy cleanup, or want the safest formula for your workspace. Choose Mr Color if you need maximum pigment strength, faster cure times, and professional-grade results. Choose Tamiya if you want a middle-ground option that is widely available and has extensive military color matching. Many experienced modelers use all three lines for different applications.

Surface Preparation and Compatibility

Before applying any Mr Hobby Aqueous paint, prepare your surface properly. Start with a clean, dry surface free of mold release agents and dust. Apply a primer such as Mr Surfacer or Aqueous Surfacer 500. Let the primer cure fully before applying color coats. The Aqueous line adheres well to polystyrene, ABS-free plastics, resin, and wood. It is not recommended for ABS resin parts due to potential cracking.

For top coats, the Aqueous line is compatible with both water-based and lacquer-based clear coats from the Mr Hobby range. Apply your clear coat only after the color coat has fully cured, which typically takes 24 hours. Forum users report that Mr Hobby Aqueous top coats in matte, gloss, and semi-gloss variants all work well over the color paints.
