A palette is:
  1. A thin board that a painter holds and mixes colour pigments on.
  2. A set of colours put on a palette, or in a more general sense, a particular set or quality of colours.
  3. In computer graphics, a mechanism where by any numeric value held by pixels may be assigned to a particular colour combination, usually specified in RGB. The primary advantage of this method is that a wide range of colour may be supported with a limited amount of graphics memory. Examples of computer graphics system using a palette is the IBM PC EGA and VGA, and the Tiki 100.
