randcolr.2da
This file allows you to make creatures or even items have random colours. You can even add your own custom colours possibilities!
There are many columns, the titles of which are... well, titles
Under each title is a unique number, this is the COLOUR INDEX, which you would type wherever you would have a reference to a specific colour (i.e. 66 is dark black, 96 is a metallic blue).
The following numbers are random colours that are possible
Here is an example from BG2 ToB:

So I could theoretically have a creature with the Colour Index for Hair set to 202, which would randomly make the hair red tinted blank (0) or dark gold 92).
Colour indices in CRE files are stored in a byte - a maximum of 256 entries can be read from randcolr.2da
Note: Random colours don't work with items; only on creatures and players.
