A
8-85 Desktop Color Primer
Color Reference Guide for C9800 - 85
The subtractive primariesare cyan, magenta, and yellow; they absorb red, green, and
blue light, respectively (as shown in the following figure). Combining any two
subtractive primaries creates a new color that is relatively pure or saturated. For
example, you can make red by combining magenta and yellow, which absorb green and
blue light, respectively. White occurs when no colorant is applied. In theory,
combining all three subtractive primaries yields black, but due to deficiencies of cyan,
magenta, and yellow colorants, combining these three primaries actually yields a
muddy brown. Black colorant is added to compensate for the deficiencies of cyan,
magenta, and yellow colorants. Consequently, color printing uses four process color:
Cyan, Magenta, Yellow, and blacK (CMYK). The use of black toner produces rich,
solid blacks and allows for improved rendering of black text.
