extern PALETTE default_palette;
DESCRIPTION
The default IBM BIOS palette. This will be automatically selected whenever you set a new graphics mode. The palette contains 16 basic colors plus many gradients between them. If you want to see the values, you can write a small Allegro program which saves a screenshot with this palette, or open the grabber tool provided with Allegro and create a new palette object, which will use this palette by default.
