The Color Wheel A color circle, based on red, yellow and blue, is traditional in the field of art. Since then, scientists and artists have studied and designed numerous variations of this concept. In reality, any color circle or color wheel which presents a logically arranged sequence of pure hues has merit.
Primary Colors: Red, yellow and blue In traditional color theory (used in paint and pigments), primary colors are the 3 pigment colors that can not be mixed or formed by any combination of other colors. All other colors are derived from these 3 hues.
Secondary Colors: Green, orange and purple These are the colors formed by mixing the primary colors.
Tertiary Colors: Yellow-orange, red-orange, red-purple, blue-purple, blue-green & yellow-green These are the colors formed by mixing a primary and a secondary color. That's why the hue is a two word name, such as blue-green, red-violet, and yellow-orange.
