No, Colour on eInk is nearly as old as eink. Either you have very pastel shades and a little darker or very dark and better colour. Recent panels sacrifice colour saturation for brightness, but still contrast and sharpeness of text is worse than regular panels.
Also either resolution is 1/3rd in one direction or 1/2 in both directions.
It's physics. It's only possible via an R G & B filter. With decent colour that gives less than 1/6th brightness as the light has to pass red, green or blue dots twice. A front light helps the brightness.
Print on paper works because it's Cyan, Yellow, Magenta and Black as a minimum in layers. Quality printing uses more colours. Photo slides are also CYM in layers. LCDs work because you can just have a x4 or x5 brighter backlight, light only passes once and colour LCD or OLED use multiple sub pixels.
Also eink only does nearly black, nearly white and 14 shades of grey. An LCD or OLED can to 250 to a 1000 "shades" of each pixel. Thus eink is inherently either dark or very pastel (or between the two) and
4096 maximum variations of colour / hue / brightness / greys / saturation etc instead of the 250 thousand to 16 million of LCD and 16 Million of OLED.
So only some different technology to eink can give decent colour. Physics and mathematics.
