MCGA and VGA
The Multicolor Graphics Array (MCGA), Video Graphics Array (VGA) used a 6-bits per channel, 64 levels Digital-to-Analog Converter (DAC) to give an 18-bit RGB palette (262,144 colors),
from which can be selected any two (in MCGA 640×480 graphic mode), 16
(in VGA 320×200, 640×200, 640×350 and 640×480 graphic modes) or 256 (in
MCGA 320×200 graphic mode) at a time.[3] They both provided full compatibility with CGA modes, while VGA included all the EGA modes as well as the MCGA modes.

In this times, all the manufacture of the computer do not produce again the type of CGA,XGA,MCGA.
Super VGA (SVGA)

resolutions (800×600, 1024×768) in both 16 and 256 picked colors from
the VGA 18-bit RGB palette, depending on the model and the manufacturer. Also, some SVGA cards support 15- and 16-bit RGB Highcolor modes, with 32,768 or 65,536 simultaneous colors on screen in 640×480 and higher resolutions. Some later models reach the 24-bit RGB True color modes.
