Cool, and thanks for the explanation. Gotten interested in retro software recently, so may actually be helpful for trying to set up pictures in some of the retro consoles. Most do tend to be limited to foreground / background. The stuff listed here [1] is pretty representative of what's being dealt with.
Note: If you happen to know how to do multi-color dithering with some of these that would actually make significant improvements on some of these old picture hardware tests.
