Secondary colors are the colors that result from the color mixing of two primary colors. In the case of the CMYK color model, the secondary colors are red, green and blue; in the RGB color model, they are cyan, magenta and yellow.
If two primary colors are mixed to 100 %, a secondary color is obtained. In both color models, the secondary color of one color model corresponds to the primary color of the other color model. Approximately 160 different shades can be created for secondary colors by mixing two primary colors.
