General information about color
Brightness is the degree of lightness in a color, as com-
pared with another color, which makes it a light color or a
dark color. For example, when comparing the yellow of a
lemon and the yellow of a grapefruit, it is obvious that the
yellow of the lemon is brighter. But what about when
comparing the yellow of a lemon and the red of a bean?
Obviously, the yellow of the lemon is brighter. Brightness
is this degree of lightness that enables comparison re-
gardless of the hue.

Everybody has an idea of what hue an object has, for example, an apple is red,
a lemon is yellow, and the sky is blue. Hue is the tint by which the color of an
object is classified as red, yellow, blue, etc.
What makes the difference between the yellow of a lemon
and the yellow of a pear? By saying that the lemon is a
more vivid yellow and the pear is a duller yellow, the dif-
ference between the two colors is stated in terms of sat-
uration, as opposed to brightness. As opposed to hue
and brightness, saturation is the characteristic that indi-
cates the degree of vividness.
