do you mean latency on a color screen? (my experience with color eInk is that it adds quite a lot of latency)

The current colour kindles and kobos don't use real eink colour. It's just a bw screen with lcd colour overlay (eink kaleido)

The real colour screens are used on the remarkable (eink gallery) and they are indeed slow for full page updates though remarkable seems to have done a lot of smarts for local updates while drawing.
