HUES are the 12 purest & brightest colors with Primary Colors, Secondary Colors, and Tertiary Colors. TINTS (aka Pastel) is any color with white added. SHADE: any color with black added. TONE: is created by adding gray.
Complementary (also known as supplementary or contrasting) colors are colors that sit opposite of each other on the Itten color circle. The combination of such colors creates a vivid and energizing effect, especially at maximum saturation.
