Under 256 (8-bit) colour modes, each pixel on screen is stored as one byte (8-bit). Unlike the "'''Direct Colour'''" modes (15/16-bit hi-colour and 24/32-bit true-colour modes, 8-bit colour mode is an "'''Indexed Colour'''" mode) the contents of the 256 colour slots in 8-bit modes need ''not'' be fixed, but instead, each of the slots can be set to ''any'' of the available 262,144 colours at one time (the VGA/MCGA base palette), so you can make variations to the colours displayed to suit your needs. | Under 256 (8-bit) colour modes, each pixel on screen is stored as one byte (8-bit).
