Secondary color

From Wikipedia, the free encyclopedia

A secondary color is a color made by mixing two primary colors in a given color space. Examples include the following.

[edit] Light (RGB)

       
red (●) + green (●) = yellow (●)
green (●) + blue (●) = cyan (●)
blue (●) + red (●) = magenta (●)
 

[edit] Pigment (CMY)

       
cyan (●) + magenta (●) = blue (●)
magenta (●) + yellow (●) = red (●)
yellow (●) + cyan (●) = green (●)

This is often referred to as CMYK where K stands for black. In theory, solid overlapping layers of C, M, and Y ink produce black. In reality the outcome is dirty brown so the black ink replaces the other three layers. See undercolor removal.

[edit] Traditional Painting Prescripts (RYB)

       
red (●) + yellow (●) = orange (●)
yellow (●) + blue (●) = green (●)
blue (●) + red (●) = violet (●)
 

In the RGB color space the colors are added, thus you start with levels of dark colors which are added to produce lighter colors. RYB uses pigments, which are not added, and thus combining colors using the RYB color system will result in a darker color.
