A-89 The properties of color
Like the sun, most light sources we encounter in our daily
environment emit a mixture of light wavelengths, although the
particular distribution of wavelengths can vary considerably. Light
from a tungsten light bulb, for example, contains much less blue
light than sunlight. Tungsten light appears white to the human
eye, which, up to a point, can adjust to the different light sources.
However, color objects appear different under tungsten light than
they do in sunlight because of the different spectral makeup of the
two light sources.
The mixture of light wavelengths emitted by a light source is
reflected selectively by different objects. Different mixtures of
reflected light appear as different colors. Some of these mixtures
appear as relatively saturated colors, but most appear as grays or
impure hues of a color.
