Game Boy Color/Color Palettes used for original Game Boy games

When playing an original Game Boy game on a Game Boy Color or Game Boy Advance (including the Game Boy Advance SP and the Game Boy Player), the user can choose which Game Boy Color color palette is used. This is achieved by pressing certain button combinations, namely either A or B (or neither) and a direction key while the Game Boy logo is displayed on the screen.

These palettes each contain up to ten colors. In most games, the four shades displayed on the original Game Boy would translate to different subsets of this 10-color palette, such as by displaying movable sprites in one subset and backgrounds, etc. in another. The grayscale (Left + B) palette produces an appearance essentially identical to that experienced on the original Game Boy.

Some licensed Game Boy games have a special default palette. Pokémon Red and Blue use primarily red and blue palettes, respectively.
