The Papyrus Palette Format is a minor variation of a standard 6-bit VGA Palette file. Instead of containing a fixed number of palette entries, these files may contain any number of colors from 1 to 256. This allows the game to leave existing palette data in place and replace only the subset of entries specified in the palette file.
