Watercolors are meant to be mixed. While many watercolor sets have flip tops that can serve as mixing wells, a separate palette opens up another world of rainbow possibilities. A watercolor palette allows you to save your custom shades for easy reactivation. Unlike acrylic or oil paints, which are unusable once they dry on the palette, dried watercolor pigments can be revived simply by adding water.
