A color palette, or simply palette (also known as a "colormap" or "color index"), is a lookup table of color values. It most frequently used for simple image compression, but can also be used for other purposes. For example, 
GoldSrc reads from a palette to know what color to render legacy particle effects from 
Quake.
Uses:
- Most stuff in Quake and
Quake II - Per-image compression in GoldSrc
- Particle effects and WON console in GoldSrc.
Note:These use palette.lmp, which is the same format as in Quake 1.palette.bmpis entirely unused.
DXT block compression (palette for each 4x4 block)- infected shader in
Left 4 Dead 2 - $lightwarptexture
