CGA "More Color" mode
Indicates IBM games which feature more than 4 colors at a time in CGA 320x200 graphics mode with an RGB monitor. Normally, only 4 colors were possible. Some games worked around this limitation by altering the color palette at particular scan lines. Unlike with some systems (such as the Atari 8-bit computer line) there was no hardware support for accomplishing this. As such, the technique is typically very hardware and/or timing sensitive and most games won't display the additional colors correctly (if at all) on non-CGA cards or on systems that don't have the CPU speed the game targeted (usually a 4.77 MHz 8088). The term was taken from the California Games menu selection option.
