Key features & specs

How it compares

When compared to entry-level student watercolor sets, the Cotman series offers significantly higher lightfastness and less filler, resulting in cleaner color mixes. Unlike traditional palettes that often utilize honey or ox gall as wetting agents, this specific Winsor & Newton set uses synthetic alternatives to ensure a 100% vegan formula. It offers a more durable housing than tin-based palettes, which are prone to rusting over time when exposed to heavy moisture.

How to use it

1. Open the pocket box and detach the mixing tray to expand your working surface.
2. Use the included collapsible brush or a water brush to activate the dry half-pans with a small drop of water.
3. Layer colors on the lid's integrated mixing wells to achieve secondary and tertiary hues.
4. Allow the pans to air dry briefly before closing the box to maintain pigment longevity.
5. Clean the integrated plastic palette with a damp cloth or sponge after each session to prevent staining.
