Worth noting that Kaleido and ACeP are very different.
Kaleido is effectively an RGB LCD in front of an E-Ink screen - you get color at 1/3 the resolution of black and white, but "normal" refresh rates. This accounts for all of the multi-color e-ink readers on the market now.
AcEP is 4 pigments per cell, so you get full resolution and better saturation and contrast, but terrible refresh rates. Last I saw for ACeP it was something like 15 seconds. Presumably this 2nd generation is much faster, but I haven't seen anything that actually says how fast.

- Groxx 6y agoNot with Kaleido, it's a normal monochrome eink screen underneath. The color filter on top changes in something like 1ms, it's invisibly fast. ACeP and the other black/white/(red|yellow) "color" inks do require multiple cycles though, and yeah - wildly unusable for reading purposes.
- zimpenfish 6y agoI have a Pocketbook Colour which uses E Ink Kaleido and it takes multiple refreshes to correctly display colours - there's 3 or 4 flashes on the coloured areas. Go to about 3:57 on this video and watch the book covers flash on and off as they do multiple refreshes - easier at 0.25x but still visible in real time. https://goodereader.com/blog/product/pocketbook-color-e-reader https://goodereader.com/blog/product/pocketbook-color-e-read...
