Graphics modes with low color depths (generally, from 4 to 8 bits) usually have a modifiable palette, also referred to as pseudocolor palette, that contains indices to the full palette of the display hardware. For instance, in the 256-color modes of the original VGA, each of the colors can be chosen from a total palette of 262,144 colors. Pseudocolor allows images comprising a small number of colours to be stored using a relatively modest amount of graphics memory. Color depth is a computer graphics term describing the number of bits used to represent the color of a single pixel in a bitmapped image or video frame buffer. ... VGA redirects here. ...


Notable computer graphics systems extensively (or even exclusively) using pseudocolor palettes include EGA and VGA (for the IBM PC) and OCS and AGA (for the Amiga). The Enhanced Graphics Adapter (EGA) is the IBM PC computer display standard specification located between CGA and VGA in terms of graphics performance (that is, colour and space resolution). ... Video Graphics Array (VGA) is a computer display standard first marketed in 1987 by IBM. VGA belongs to a family of earlier IBM video standards and largely remains backward compatible with them. ... The Original Chip Set (OCS) was a chipset used in the earliest Commodore Amiga computers. ... Advanced Graphics Architecture (AGA) was the name used for the improved graphics chipset of the third generation Amiga computers at the beginning of the 1990s. ...
