colour


#@graphics@# (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.
