Does anyone have a primer on multi-color dithering? I made a fun dither like program for monotone style dithering, but I'm not really sure how to adapt it to color palettes with more than two tones.
Color dithering is very similar black and white dithering, the difference is that instead of 2 colors (black and white), you have n colors, and you want to find the one that has the shortest distance to the current pixel. There are various formulas[1] to determine which color is closest, and which formula you choose will have an effect on the results. I built a dithering app[2] that lets you choose the distance formula, so you can see for yourself.
