colors used in

RGB triplet or in
hexadecimal format (a
hex triplet). They may also be specified according to their common English names in some cases. Often a
color tool or other
graphics software is used to generate color values. In some uses, hexadecimal color codes are specified with notation using a leading
number sign (#). A color is specified according to the intensity of its red, green and blue components, each represented by eight
bits. Thus, there are 24 bits used to specify a web color, and 16,777,216 colors that may be so specified.
