Current rendering algorithm is inapropriate,  http://en.wikipedia.org/wiki/Floyd-Steinberg_dithering should behave much better on e-ink devices.

  • Owner set to t3d
  • Status changed from new to accepted
  • Component changed from misc to madeye

That's because white in this picture isn't pure white (in HTML notation it is #fdfdfd and not #ffffff) and madeye's display algorithm is poor and not optimised for e-ink for now. Of course that should be changed.
