DotChroma

Color picker from any photo. Palette, HEX/RGB/HSL codes, WCAG contrast — all on device. Colors depend on lighting; that's expected.

DotChroma turns any photo into a precise color toolkit — entirely on your iPhone or iPad, no account, no cloud.

TAP TO SAMPLE Import a photo or capture one with the camera. Tap anywhere to identify a color. Use the magnifier for pixel-perfect picks.

DOMINANT PALETTE Automatically extract the main hues from your image and tap any swatch to set it as the active color.

SESSION HISTORY Keep track of every color you sample. DotChroma automatically resumes your last session.

COLOR HARMONIES Generate 9 schemes from any sampled color: complementary, analogous, triadic, split complementary, tetradic, monochromatic, tints, shades, and tones. Copy a code with one tap, or export the whole set.

DEVELOPER CODES Copy HEX, RGB, HSL, SwiftUI, UIKit, CSS, or SCSS. Export your palette or history as plain text or CSV.

WCAG CONTRAST Check readability on white or black backgrounds. Contrast ratio and AA/AAA compliance (WCAG 2.1).

COLOR NAMES — 13 LANGUAGES Standard mode (localized CSS names) or Natural mode (xkcd palette). French, English, German, Spanish, and 9 more languages.

IMPORTANT — LIGHTING MATTERS Detected colors depend on ambient light, the photo's white balance, and your display settings. The same wall can look different in shade, direct sunlight, or warm lamp light. That's not a bug — DotChroma accurately reads the pixels in your image. When matching real paints, fabrics, or physical samples, sample under stable, consistent lighting.

COMPLETE PRIVACY Your images never leave your device. No account. No ads. No tracking. Everything runs on-device.

Perfect for designers, developers, interior stylists, and anyone who needs trustworthy color values from real-world photos.

The free version includes 10 image imports per month. Sampling, dominant palettes, color names and contrast checks are unlimited on the images you load.

DotChroma Pro is a one-time purchase — no subscription, no account. It unlocks unlimited imports, color harmonies, developer code export, and full palette export.
