n This is a smaller, travel-sized version of the traditional Stephen Quiller palette. Designed around his color theories, the Quiller palettes are arranged for mixing colors based on the color wheel. A circle of 12 wells can hold all primary, secondary, and tertiary colors. There are wash/mixing basins on the side and center, along with 12 extra wells for additional colors. Measuring approximately 11 x 14 inches, this travel version has a lid and fits inside most French easels.
