The reflectance of the coloured ink pattern reduces contrast.

Sometimes even 4 bit EGA (16 ) or 8 bit VGA (256) will look better than kaleido. I had an Amiga too. It certainly was better than VGA for colours. But the Kaleido CFA unlike CRT phosphors, or any kind of colour LCD, only partially covers each mono eink pixel so there are only pastel shades at best. Nor can the palette be adjusted. Also if the mono eink panel calibration isn't perfect you don't get the 14 grey levels plus black and white, there might only be 12 levels. Judging from photos the Kaleido is far worse than 4096 Amiga or other colour display systems only having the variation from pastel to shades of murk.
