One way to create a color palette is to use the color wheel. Adobe has an interactive color wheel at color.adobe.com. You can use the sliders to find a particular color, and then select a color rule to see its complement on the color wheel or the two colors that go along with it to form a triad. You can also generate an analogous, monochromatic, or compound pattern based on the color. (Check out the color theory reference chart to see how those color relationships are formed.)
Pixar Animation Studios and Khan Academy collaborated to create a series of free online courses about topics related to movie animation. One of their courses is called “Color science.”
