GameBoy Advance colors are stored as 16-bit integers using the 15-bit BGR555 format (xBBBBBGGGGGRRRRR). This allocates 5 bits each for Red, Green, and Blue (values 0-31), yielding 32,768 distinct colors, while the most significant bit is ignored. This tool handles bidirectional conversion between individual channel sliders and 16-bit hex outputs. Thank you for using this tool in your GBA development workflow.
