The primary colors are RED, YELLOW, and BLUE.
Primary Colors: Red, yellow and blue In traditional color theory, 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.
