Palette Knives Mix Your Colors
These are used to mix your colors on the palette. Knives come in many shapes, sizes and uses. These shapes are well suited to the mixing of colors. You only need one to start. The top one is the most useful. With your knife take portions of the colors you want to mix to a clean spot on your palette. Then using the knife stir the colors together turning the mixture over often. Wipe the knife clean and mix the color again to make it even.
Palette knives clean the palette at the end of a session. Remove the left over colors from your palette with a palette knife and put them in a can for future safe disposal.
