public class NesPalette

extends Object

This class defines the built in 64 color palette of the NES. Only 52 of those colors are unique. It allows access to predefined colors as both Java specific Color objects and as raw RGB integer values. It also supports updating the palette dynamically which the NES does not.

Originally part of the MonkeyNES project.
