DESKTOP COLOR PRIMER 65 A familiar device that is based on this color model is the computer monitor, illustrated in the following figure. Monitors have red, green, and blue phosphors that emit varying amounts of light to display a given color. Scanners create digital representations of colors by measuring their red, green, and blue components through colored filters. Subtractive (CMY and CMYK) color The subtractive color model is the basis for color printing, color photographic prints, and transparencies. While the additive color model simulates the visible spectrum of color by adding light of three primary hues, the subtractive color model starts with a "white" or neutral light source containing light of many wavelengths. Inks, toners, or other colorants are used to selectively absorb (subtract) certain wavelengths of light that otherwise would be reflected or transmitted by the media in use.

A familiar device that is based on this color model is the computer monitor, illustrated in the
following figure. Monitors have red, green, and blue
phosphors
that emit varying amounts of
light to display a given color. Scanners create digital representations of colors by measuring
their red, green, and blue components through colored filters.
Subtractive (CMY and CMYK) color
The subtractive color model is the basis for color printing, color photographic prints, and
transparencies. While the additive color model simulates the visible spectrum of color by
adding light of three primary hues, the subtractive color model starts with a “white” or neutral
light source containing light of many wavelengths. Inks, toners, or other
colorants
are used to
selectively absorb (subtract) certain wavelengths of light that otherwise would be reflected or
transmitted by the media in use.
