Colour mapping

With low colour depths (up to 8-bit) it is practical to map every colour to a binary code.

  • 1-bit colour mapping - (2 colours) monochrome, often black and white.
  • 2-bit colour mapping - (4 colours) CGA - used by many early home computers with TV displays 4-bit colour mapping - (16 colours) - used by CGA (Colour Graphics Adapter) graphics cards
  • 8-bit colour mapping - (256 colours) - used by VGA (Video Graphics Array . . .
