Color wheel
The secondary colors are on all color wheels. Secondary colors are made by mixing the primary colors of light together. The secondary colors of light are the primary colors of pigment on the printer's color wheel--the color wheel used for color printing. These three colors are called the subtractive colors.  They are magenta (a bright pink), yellow and cyan (a light greenish blue).  The primary colors of light are the secondary colors on the "printer's color wheel".  The three primary colors of pigment can be mixed to make red (magenta and yellow), green (yellow and cyan), and blue (cyan and magenta), but they do not appear as bright when they are made with pigment instead of light.  The secondary colors can be mixed with the primary colors to make tertiary colors.
