About & scope
A narrow preflight before real hardware testing.
Pocket Palette QA is an independent browser tool for inspecting APGB palette bytes and mechanical luminance relationships. It exists because a structurally valid palette can still make important objects hard to distinguish in a specific scene.
What it checks
The tool verifies the exact 56-byte layout and footer, shows all four four-color groups plus LCD-off, checks dark-to-bright ordering, and warns about low adjacent or object/background luminance separation.
What it cannot prove
It does not emulate a display, cartridge, core, firmware, game scene, color-vision condition, ambient light, or real device. A clear report only means the supported byte and luminance checks found no issue.
