# Game Boy Color Bar and Wheel Test Images

The first two color bar patterns (RGB, CMYK) have exactly 32 colors in each horizontal gradient. 

- For some screens, such as OEM non-backlit GBC, it may be difficult to distinguish between adjacent color gradations.

- If colors are missing or misaligned to the grey reference blocks then the screen or emulation color depth may not be accurate or may be clipped.

- Some emulators may shift the rendered GBC colors up or down a value before displaying.
