Colorimeter: Live Color Picker

Turn your iPhone into a pocket colorimeter. Point the camera at any surface — a flower, a wall, a fabric swatch — and read its color instantly, in every format you need.

POINT. READ. CAPTURE. • Live color readings straight from the camera viewfinder • Values in HEX, RGB, HSB, Lab and CMYK, updated in real time • Freeze the reading with one tap to examine or save it calmly • Full-screen camera mode with overlay controls • Tactile feedback on every capture

SAMPLE FROM YOUR PHOTOS Pick any image from your library and tap a point to read its exact color. Perfect for moodboards, references and pictures you took on site.

YOUR PALETTE, ALWAYS WITH YOU Every captured color lands in your History: a clean grid of swatches with HEX codes, ready to copy or share. Your collection is stored with iCloud, so it follows you across your devices.

PRO-GRADE CALIBRATION Ambient light fools cameras. Colorimeter's Accurate mode fixes that: • Calibrate with any 18% neutral gray reference card • The app estimates the scene's real illuminant from the gray • A Bradford chromatic adaptation (in LMS cone space) corrects every reading toward your target illuminant, D65 or D50 • Create and manage a profile for each lighting condition • Calibrated captures store Lab values you can trust

MADE FOR DESIGNERS, PAINTERS AND MAKERS • Choose your preferred format for quick copy • Adjustable sampling patch size for noisy surfaces • Light, dark or system theme • Modern, fast, native SwiftUI app

HONEST BY DESIGN • 100% ad-free — no banners, ever • No accounts, no tracking, no analytics • Your colors stay in your private iCloud

A note on accuracy: readings are indicative. A phone's RGB sensor is not a spectrophotometer, and metallic or iridescent finishes are out of reach for any camera. For everything else, calibration gets you remarkably close.
