Coop Vision
Point your camera at a thread, a wall or a fabric. Coop Vision reads the colour and tells you the nearest DMC or RAL code, how close the match really is, and what to buy.
Measured, not guessed
Colours are compared in CIE Lab using CIEDE2000 — the same difference metric the printing industry uses — and the app calibrates against a white card so a warm lamp does not turn your greys yellow.
The match distance is always shown rounded to a whole number. A phone camera reading an unknown surface under unknown light is good to a few units at best, and showing decimal places would be inventing precision that is not there.
Works offline
Catalogues live on your device, so measuring works in a shop basement with no signal. Sync, when you turn it on, keeps your palettes across devices and through a reinstall.
