Palette

The color palette used by Half-Life's particle effects, which is a modified version of the Quake I palette.

A color palette, or simply palette (also known as a "colormap", "color index", or "color lookup table"), 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.bmp is entirely unused.

• P8 texture format in XTF files
• DXT block compression (palette for each 4x4 block)
• infected shader in  Left 4 Dead 2
• $lightwarptexture
