> The main drawback with color E Ink screens is they look darker than regular B&W screens because of a color filter layer that is applied over the top of the screen, which makes the contrast appear lower. Kaleido color screens are really just regular black and white E Ink Carta screens with a fancy passive filter over the top (that’s why color resolution is lower than black and white resolution).
