Small utilities for frontend developers and designers, built on the same colour and contrast code Stele runs on a capture. They work in your browser, with no account and nothing uploaded.

• contrast checker

  A text and background pair against WCAG 2.2 and APCA at once, with pass or fail for every text size.

• palette extractor

  Dominant colours out of any image as hex and OKLCH, with perceptually identical shades merged.
