The game uses a 256 color palette. Each individual color is made up of three numbers. They tell how much red, green, and blue is mixed to create the color. Windows palette files usually range from 0 to 255. Keep in mind that if you want the colors to shade properly, a bright blue will need darker blues to fade to before fading to black.
