Paint Color Match: HEX Picker

Paint color match from your camera or photos: pick a color, read its HEX code and see how close each sample is to your reference. Matching touch-up paint, yarn or a brand swatch is easier when the color becomes a number you can check, so every color comes in six formats and can be kept 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 applies an approximate correction for 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 (approximate) and CIE Lab for every color. Tap the swatch to share the HEX code with its color names; the other five values can also be selected as text.

▶ 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.

▶ ON YOUR DEVICE
• 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/HEIF photos are not read directly. Save the picture as JPEG or PNG first, for example by turning off the high-efficiency photo format in your camera settings.
• Color names are approximate and paint brand codes are not included.

Color Match now wears a new icon: a fan of paint swatches beside an eyedropper letting fall a coral drop. Look for it on your home screen; your palettes and every color saved in them carry over as they are.
