Game Boy Color Picker is meant to help with colorizing Game Boy games, or developing homebrew.
It runs on Game Boy Color, Super Game Boy, and Game Boy Advance emulators, or on real hardware using a flash cart. This allows you to select four colors at a time from any of the 32,768 the hardware can display, and immediately see what they look like and the numeric value you need for your project.
It also saves the colors at the beginning of the .sav file for use with tools that take GBC/SNES formatted binary color palettes.
