The old Gameboy has a background map of 8x8 tiles, and up to 40 8x8
sprites, all in four-color greyscale.  The GB Color has that the same way
- you're right, it's 4 colors per 8x8 block and, independently, four
colors per sprite.  The Gameboy CPU is a custom Z80 (with stuff like I/O
removed) running at 4 MHz; the GB Color CPU can run at either 4 or 8 MHz.
