And now that I have a structured palette I know what bits are red, green, and blue, and so I can easily do cool effects using PUTs binary operations, OR, AND, and XOR

Fuck yeah this is going so well!

btw here is the FF7 with ordered dither but no subpixel dither compared to the one with subpixel dither, and the details just vanish completely. not even a contest

huh. interesting. i think the ordered dither was actually interfering with the subpixel dither, because i like the one without the ordered dither (left) better than the earlier one with the ordered dither on top of the subpixel dither (right)

i added a 0-1 scalar that biases colors towards non-dithered to make things less busy. here's factors 0, 0.25, 0.5, and 0.75 in order:

what's shocking me the most is that images with a lot of blues in it still work really well, despite only having 2 bits of blue (so 0, 85, 170, and 255)
