resulting color is black. When the value of each
component is 0, no color is added to the
surface, so the surface itself is revealed — in
this case, the white paper. Black (K) is included
in the color model for printing purposes
because black ink is more neutral and darker
than blending equal amounts of C, M, and Y.
Black ink produces sharper results, especially
for printed text. In addition, black ink is usually
less expensive than using colored ink.

CMYK color model. Black is the result of combining the
three CMY colors at their maximum intensities.

HSB color model

The HSB color model uses hue (H), saturation
(S), and brightness (B) as components for
defining color. HSB is also known as HSV (with
the components hue, saturation, and value).
Hue describes the pigment of a color and is
expressed in degrees to represent the location
on the standard color wheel. For example, red
is 0 degrees, yellow is 60 degrees, green is 120
degrees, cyan is 180 degrees, blue is 240
degrees, and magenta is 300 degrees.
Saturation describes the vividness or dullness
of a color. Values of saturation range from 0 to
100 and represent percentages (the higher the
value, the more vivid the color). Brightness

describes the amount of white in the color. Like

saturation values, brightness values range from

0 to 100 and represent percentages (the higher

the value, the brighter the color).

Grayscale color model

The grayscale color model defines color by

using only one component, lightness, which is

expressed in values that range from 0 to 255 in

8-bit images. The value range varies,

depending on the bit rate of the image. Each

grayscale color has equal values of the red,

green, and blue components of the RGB color

model.
