HueComb: colour tools that show their working

Editorial interest 84/100 Selection signal · not a rating of the site

A browser-based set of colour tools for checking contrast, comparing colours, simulating colour-vision deficiency, and building palettes.

Landing page captured for the 2026-10-06 issue.

For: Designers checking interface colours and palettes
Worth noticing: The site says its colour-difference formula is checked against 34 published reference pairs and APCA against 900 pairs from its reference implementation.

Field notes

The contrast checker distinguishes body text, large text, and icons or borders, and shows both WCAG 2.1 and APCA results. For a failing pair, the page describes a search in OKLCh for the nearest passing colour of the same hue, while noting that some backgrounds have no solution. Image palette extraction is described as running in the browser, and the site says dropped files are not sent elsewhere.
