The displays can show black, white and red. He picked a good image for that palette. Still, the dithering was surprisingly effective.

- TylerE 4y agoSounds like the early two color process in Hollywood… they got red (for skin tones) and a sort of teal blue green that could sorta do plants and sorta do sky, but wasn’t real convincing at either.

- stavros 4y agoDithering is amazing. I built a display to show my calendar: https://www.stavros.io/posts/making-the-timeframe/ https://www.stavros.io/posts/making-the-timeframe/ When testing it out, I tried to show a grayscale image, because the display supports four tones, but it came out horrible. Then I displayed a dithered two-tone image (black and white) and it was much, much better: https://www.stavros.io/posts/making-the-timeframe/dithered.jpg https://www.stavros.io/posts/making-the-timeframe/dithered.j... I wonder if there are any arbitrary-palette dithering algorithms that I could try, it would be great to be able to use the other two tones and still dither.
