colour

<graphics> (US "color") Colours are usually represented as RGB triples. 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 bitfields 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.
