colour

(US "color") Colours are usually represented as

{RGB} triples in a {digital} {image} because this corresponds

most closely to the electronic signals needed to drive a

{CRT}. Several equivalent systems ("{colour models}") exist,

e.g. {HSB}. A colour {image} may be stored as three separate

images, one for each of red, green, and blue, or each {pixel}

may encode the colour using separate {bit-fields} for each

colour component, or each pixel may store a logical colour

number which is looked up in a hardware {colour palette} to

find the colour to display.

Printers may use the {CMYK} or {Pantone} representations of

colours as well as RGB.
