Features
One app for the whole job - identify, simulate, correct, compare and save color - that keeps working without a connection. The core is free, offline and account-free; a one-time Pro unlock adds the extras below.
Free, for everyone
- Color identification (camera, image or a typed value) with name + HEX/RGB/HSL/LAB, voice output, and a lighting-fix toggle for truer readings
- Three naming vocabularies - everyday, common (crowd-sourced) or 30,000 creative names
- CVD simulator: protanopia, deuteranopia, tritanopia at adjustable severity
- Correction filter (daltonization) - make confusable colors easier to tell apart, live or on an image
- Ishihara-style color-vision screening (not a diagnosis)
- Match or clash - compare two colors, with a 'could a color-blind friend still tell them apart?' check
- WCAG contrast checker with AA / AAA pass-fail
- Eyedropper - read any pixel from an uploaded image
- Show a friend what I see - side-by-side normal vs CVD view, shareable
- Palette from image - pull out the dominant colors
- Saved color library with your own names and notes, kept on your device
- Library backup & restore - export your whole library to a file and bring it back on another device or a fresh install
- Share your screening result or a palette as a branded image card
- Installable and works offline - no app store, no account
With Pro
One-time £10- Unlimited saved library (the free library holds up to 10 colors)

- Full image palettes - see every colour pulled from a photo (the free tool previews the top 5), and reorder them by hand
