That’s not really correct, modern color eink displays actually change color, there’s different pigments inside each cell and others are created visually using dithering. Only the older type are monochrome displays with a color filter behaves like you’re describing.
replyMulti-pigment panels exist but in practice nearly all color e-readers still use the filter-based panels, because they are so much cheaper. There are zero Kindle or Kobo models with the multi-pigment technology.
replyThe ReMarkable devices are E Ink Gallery 3 multi pigment display, I have one on my desk.
replyI did say nearly all, and the price of the ReMarkable Pros reflects on how expensive the Gallery panels still are.
replyYeah, E Ink Gallery is the only real exception to the rule with full color support. (The store signage can also change colors, but they don't support color mixing, so there are just three or four colors in total.) Unfortunately, even after 10 years, E Ink Gallery is still far behind colored paper in quality. I think fundamentally their approach to e-paper (electrophoresis displays) is just not suited for full color.
