Colour Palette
Definition: Also called a colour lookup table (CLUT), index map, or colour map, it is a commonly-used method for saving file space when creating colour images. Instead of each pixel containing its own RGB values, which would require 24 bits, each pixel holds an 8-bit value, which is an index number into the colour palette. The colour palette contains a 256-colour subset of the 16 million unique displayable colours.
