What is the best palette for Watercolour?  As watercolours s are re-wettable which means that if they dry out on the palette they are still usable at a later stage. Watercolour palettes are designed with “wells” on the palette to store the paint in. In doing so the paint can remain on the palette and simply be topped up from a paint tube as it runs low.  

The basic differences across the full range of watercolour palettes is the number of wells on the palette and single or compartmentalised mixing areas. The other significant difference is whether the palette has a cover to it. 

the Derivan Leakproof Watercolour Palette Travel Paint Tray has multiple mixing areas, for watercolour, Gouache.

This palette keeps your paint fresh as this paint tray palette has a silicone airtight seal on the lid, which is great for keeping the paint pans moist, and easy to clean. 
Keep your colours tidy and organized, great for plein air travelling trips.
