# E Ink Kaleido 4

9 Hacker News commenters recommended E Ink Kaleido 4 and 10 criticized it, November 2025 to November 2026. It was recommended in 1 of 13 months.

**Verdict:** People who read articles and papers find its color E Ink screen useful and easy on the eyes in sunlight, though critics say its contrast and color quality lag behind black-and-white e-readers.

## What people warn about

- Contrast worse than black-and-white readers (4 comments): "For pure reading of text it provides minimal benefit (color highlighting and cover art, mostly) while costing contrast ratio and dollars." ([source](https://news.ycombinator.com/item?id=50110954)) "50% contrast improvement is significant, but it's from a base of only around 1:10, so will still be fairly low in absolute terms" ([source](https://news.ycombinator.com/item?id=50109760)) "even with 50% improvement the contrast is still significantly worse than on the BW readers" ([source](https://news.ycombinator.com/item?id=50115086))
- Color adds little for pure text (3 comments): "For pure reading of text it provides minimal benefit (color highlighting and cover art, mostly) while costing contrast ratio and dollars." ([source](https://news.ycombinator.com/item?id=50110954)) "Not really if you want to read color content. If your usecase is pure B/W, it's better." ([source](https://news.ycombinator.com/item?id=50113424)) "I don't think the color (at lower resolution) is worth it for me." ([source](https://news.ycombinator.com/item?id=50110069))
- Dark screen with low resolution (3 comments): "Personally I find the lower resolution and contrast to be unacceptable." ([source](https://news.ycombinator.com/item?id=50124897)) "All Kaleido color displays are really really dark, even outdoors" ([source](https://news.ycombinator.com/item?id=50113953)) "the screen swallows two thirds of the incoming light" ([source](https://news.ycombinator.com/item?id=50111530))
- Colors muted and slow to refresh (3 comments): "Quite muted colours in the past and it only really works well with a front light" ([source](https://news.ycombinator.com/item?id=50109131)) "the color isn't great, the screens are slow to refresh in an annoying way" ([source](https://news.ycombinator.com/item?id=50110126)) "Colors are as vibrant as late 90s cheap laptops." ([source](https://news.ycombinator.com/item?id=50110668))
