# E-ink / low-contrast calm

Also called: e-ink UI, calm technology design, low-contrast UI, paper display style, reader mode, Kindle style  
Era: 2007 (Kindle), design trend 2020 onward (calm tech, Readwise, Reader apps, Daylight computer)

## Traits

- greys on warm grey, like an e-paper display: no pure white, no pure black
- contrast kept moderate (5-7:1), never harsh; no saturated colour except one dim accent
- reading typography: serif body at 18-20px, long measure, generous leading
- no shadows, no gradients, minimal borders in a slightly darker grey
- controls are simple outlined shapes; states shown by fill inversion
- deliberately slow or no animation, mimicking e-ink refresh (instant swaps or 0ms)
- dithering or subtle halftone on images to mimic the display

Palette: #dedcd6 paper grey, #2f2f2d ink, #7a7975 muted, #b9b7b1 line, #c9c7c0 surface, #4a5d4f one dim green accent

Type: Literata, Bookerly-alike "Source Serif 4", Newsreader or Charter (free) for body at 19px line-height 1.7; Karla or Public Sans at 14px for UI; headings 500 at 28-36px

## Do

- keep the palette to 6 greys plus one dim accent and check every pair sits between 5:1 and 8:1 contrast
- make transitions 0ms (instant swap) or a single 200ms fade; no easing curves, no movement
- convert images to greyscale and apply a dither or 2px halftone so they belong to the surface

## Don't

- do not use white or black; the display look depends on the mid-grey paper
- do not add hover effects beyond an underline; e-ink has no hover
- do not use colour for state; use inversion (dark fill, light text)
