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.

|---|---|
| BYTE pad | Fixed; always 00 |
| BYTE startIndex | The VGA palette index at which color data from this file should be written |
| BYTE numEntries | Number of color entries in this file. A value of 00 is interpreted to mean 256 colors. |
