Additive Theory of Color
Introduction
Photography, computer monitors, and television use light to project the
colors of the visual spectrum. This technology uses the additive theory of
color.
The additive
The additive theory of color theorizes that white light contains all colors in
theory of color
the visual spectrum. The primary colors of the additive theory of color are
red, blue, and green. These colors are called primaries because they cannot
be produced by combining any other color.
Combinations of the primary
colors produce other colors. A combination of the three spectral (additive)
primaries produces white light.
Figure 2-7 shows the spectral primaries of the additive theory of color.
