Description
You see, when you open ROMs like Pokemon Yellow, the border and palette changes, except when you open GPU Viewer. It always shows GB's default B&W palette, no matter which game you are playing.
The palette in the image is glitched, in order to show what's exactly going on:

Research direction
Start by locating the GPU Viewer entry point and Gambatte's SGB palette handling, then reproduce the issue with a ROM such as Pokemon Yellow. Compare the viewer's palette with the active game's palette. Done means GPU Viewer reflects the game's SGB palette and no longer always uses the default GB black-and-white palette.
