== Primary and dimmed palettes ==

The palette entries in the '''primary''' and '''dimmed''' palettes are store as red, green, and blue planes:

* The first 256 bytes are the red components in order, the next 256 are the green components, etc.
* Each component is stored in 6-bits (0-63) and will need to be multiplied by 4 to map to the range 0-255.
* Index 0 is always transparent.

The index of the colors within the palettes are important:

== Unknown chunks (1) ==

* The '''Unknown chunks''' appears to be 32 (or 33) chunks of 1,024 bytes, representing what appears to be a non-looping animation of 32x32 pixel images.
* These chunks do not appear to use the palettes.
* These chunks are different for each palette.

== Unknown data (2) ==

The '''Unknown data''' is all of the data from the end of the '''Unknown chunks''' up until the start of the '''Shading tables'''.

* The purpose of this data is not known, but might be compressed using the same RLE method used by the game's [[SPR (Dark Reign)|sprites]].

== Shading tables ==

The '''shading tables''' comprise 192 chunks each of 768 bytes totaling 14,7456 bytes.

Each chunk appears to be the primary palette mixed 50% with another color, and each byte is an index back to the original palette of a color which most closely matches the color after the blend. It is not know what colors are being blended, or their purpose.
