Color Match: Color Picker

Matching touch-up paint, yarn or a brand swatch is easier when the color becomes a number you can check. Capture a color from the camera or a photo, read its codes in six formats and see how far each sample is from your reference. Keep what you find in palettes for the next project. ▶ CAMERA: ONE SHOT, A STEADY VALUE • Take a single still and read the color inside the marked square. Move the square anywhere on the photo and choose a small, medium or large area. • Optional white or grey card: photograph a neutral card once and the app removes the color cast of your lighting. Cards that are clipped, too dark or tinted are refused, and the unadjusted value is always kept. ▶ PHOTOS AND SCREENSHOTS • Tap any point for the exact pixel or a 5×5 average, with a magnifier loupe for precise picking. • Extract the dominant colors of a picture, from 2 to 8, each with its share in percent. • Wide-gamut photos with an embedded color profile (such as Display P3) are converted to sRGB before reading. Files the app cannot read correctly are refused instead of showing a wrong value. ▶ MATCH: IS IT THE SAME COLOUR? • Set one reference color and add up to 24 samples from the camera, photos or typed HEX codes. • Samples are ranked by Delta E 2000 (CIEDE2000), the standard color-difference formula, with a pass or fail against your tolerance (0.5 to 10, default 2). • A plain-word note explains each difference, for example darker and slightly greener. • Useful for touch-up paint, fabric and yarn, printed samples, make-up shades and brand colors. ▶ NAMES AND VALUES • Everyday color name plus the nearest web (CSS) color name. • HEX, RGB, HSL, HSV, CMYK and CIE Lab for every color, one tap to copy or share. ▶ PALETTES • Up to 100 palettes with 40 colors each. Rename, reorder and delete. • Color harmonies for any swatch: complementary, analogous, triadic, split-complementary and tetradic, plus lighter and darker steps. • Export a palette as CSV or share it as text. ▶ PRIVATE BY DESIGN • Photos are analysed on your device. Camera stills are deleted after use. No account needed. GOOD TO KNOW • A phone camera is not a measuring instrument. Lighting and screen settings change what you see, and the white card helps but cannot make a camera into a spectrophotometer. • HEIC photos are not read directly; choose the Most Compatible camera format or send the picture as JPEG or PNG. • Color names are approximate and paint brand codes are not included.
