Point your iPhone at a wall, a fabric, a flower — and read its color live in HEX, RGB, HSB, Lab and CMYK. Calibrated like a pro tool, simple like a camera.
Free. No banners, no subscriptions, no data grabs — ever.

Human vision constantly "corrects" what you see. That's why the paint swatch never matches the wall, and the photo never matches the fabric.
The same object looks warm at sunset, cold under LEDs, greenish under fluorescents. Which one is the "real" color?
Repainting a wall, reordering fabric, reprinting a batch — every wrong color guess turns into wasted time and material.
Your iPhone's camera plus real color science: measure instead of guessing, and take the number with you.
Everything happens live, on device, in the formats designers and makers actually use.
Frame anything and watch the readout update in real time. Freeze the reading when it's right, capture it with one tap.
Open any image from your library and tap a point to read its exact color. Perfect for moodboards, references, and pictures taken on site.
Every color lands in a clean visual history with its HEX code — copy, share or revisit any time, on all your devices via iCloud.
Ambient light fools every camera. Accurate mode fixes it with the same method used in photography and print.
Frame any standard gray reference card. Because it reflects all wavelengths equally, it reveals the true "white" of your scene's light.
A chromatic adaptation in LMS cone space — the same transform used by ICC color management — corrects every reading toward D65 or D50.
Calibrated captures store trustworthy Lab values. And where a phone sensor can't go (metallic, iridescent finishes), the app says so.
You're the user, not the product. Colorimeter has no ads, no tracking, no analytics and no account — your colors live on your device and in your private iCloud, where we can't see them.
Free on the App Store. Thirty seconds from now, you'll know the color of the first thing you point at.
