Choosing the right paint mixing tray matters more than many hobbyists realize — it affects color control, cleanup time, portability and even how often you’ll want to work. These recommendations come from lab-style hands-on testing, cross-checks with expert advice, and aggregated consumer feedback to identify trays that excel across common uses (watercolor, acrylics, bead-sorting, classroom use, and travel).
Considerations and Testing Method
We evaluated trays using a combination of hands-on testing, expert input, and consumer feedback. Key factors that influenced our rankings:
- Material & Durability: How well the tray resists staining, cracking or deformation (plastic grade, stainless steel quality, coatings).
- Usability in Real-World Conditions: How trays perform for paint mixing, bead sorting, and sensory activities (well depth, edge shape, flatness).
- Cleaning & Maintenance: Ease of cleaning after water-based and heavier pigments; whether disposables are a better option for some tasks.
- Portability & Storage: Stackability, weight, compactness for travel or classroom storage.
- Versatility: Use cases beyond paint — serving, bead-sorting, model-mixing, nail-art mixing.
- Value: Cost per unit relative to quality and intended use (classroom sets vs single specialized palettes).
Testing process (brief): we used each tray for multiple sessions across media (watercolors, acrylics, model paints), assessed stain resistance and shape retention, measured capacity and dimensions, and noted user comfort. We also cross-referenced Amazon/retailer reviews for common failure modes and longevity reports. This mixture of objective checks and subjective workflow testing informed the final picks.
Stainless Steel Mixing Cups
Durable stainless-steel mixing cups ideal for tiny color mixes. Compact, corrosion-resistant, and reusable — perfect for model makers, makeup mixing, and precision palettes. Inexpensive and easy to clean, they’re the go-to if you need small, reliable metal wells for repeated use.
Why it’s the Best Budget Pick
These small stainless-steel round trays are an excellent low-cost solution when you need durable, reusable mixing wells. Made from corrosion-resistant stainless steel, each 1.96-inch cup handles small volumes cleanly without staining or warping. They’re lightweight, compact, and come in a pack of 12 — great for model painters, nail artists, or anyone who mixes small pigment batches. Pros: near-indestructible, easy to clean, reusable. Cons: very small capacity and not suited to larger washes or classroom group activities.
MUZMDNI Pocket Palette
A compact, premium travel palette kit with 24 colors, three brush pens, a sketchbook and magnetic palette design. Built for plein-air watercolorists who want an all-in-one, portable watercolor solution with tidy storage and quick setup.
Why it’s the Premium Choice
This compact portable watercolor set is more than a tray — it's a complete travel kit. It pairs a small magnetic palette with a sketchbook, metal binder clip, three brush pens and a 24-color watercolor box. The build emphasizes convenience: magnets for secure palette attachment, a clip for page stability, and a mini wooden aesthetic. It’s ideal for urban sketchers and plein-air watercolorists who value portability and an integrated kit. Technical notes: palette ~5.9 x 3 in, quality paper in the sketchbook, and magnetized palette components. Trade-offs: not the cheapest per paint capacity, and the tray depth is shallow — optimized for watercolors rather than thick acrylic mixing.
20-Pack Stackable Trays
A large set of 20 stackable plastic activity trays in multiple colors. Great for teachers, group projects, and craft sessions — they balance capacity and storage convenience while holding paint, beads or sensory materials effectively.
Why it’s the Best Value for Money
This 20-piece set delivers sheer quantity, color variety, and stackability — an excellent value for classrooms, summer camps, or craft parties. Each tray is roughly 9.65 x 7.28 in with a 0.9 in depth, offering ample room for paint mixing, bead sorting, and sensory play. The stackable design saves storage space and makes setup/tear-down quick. Pros: large pack size, reliable for group use, multipurpose. Cons: thin plastic can show wear over long-term heavy use and may stain with intense pigments unless washed promptly.
Large Activity Trays
Ten large, rigid plastic art trays in five bright colors. Generous surface area and sturdy construction make these ideal for classrooms, mixed-media projects, and kids’ group activities where stability and size matter.
Why it’s the Editors’ Choice
This 10-pack stands out for balanced performance: sturdy molded plastic, large surface area (13.4 x 9.8 in), and a kid-friendly design that suits everything from finger paints to loose-parts STEAM activities. The tray size gives you workspace for color mixing and compositing without being unwieldy. In tests it resisted flexing and handled repeated classroom use better than thinner alternatives. Pros: roomy wells, five useful colors, good price per unit for quality. Cons: bulkier to store than smaller trays; not transparent (so you can’t see through the sides).
