Obang: Contrast & Paint Match

Obang is a precision color picker and toolkit for designers, developers, and anyone matching colors in the real world — sample any color from a photo, check its accessibility, and match it to real paint. No account, no tracking, everything stays on your device. SAMPLE ANY COLOR • Drag to sample the exact pixel under your finger — an eyedropper with a magnifier loupe for precision. • Instant HEX, RGB, and HSL, an approximate color name, and its hue family. • Complementary, analogous, and triadic harmonies from any color. CHECK CONTRAST & ACCESSIBILITY • WCAG 2.1 contrast ratios with clear AA and AAA pass/fail for normal and large text. • APCA (the WCAG 3 preview) for perceptual contrast. • Fails a check? Obang suggests the nearest passing color so you can fix it in seconds. • Preview palettes through deuteranopia, protanopia, and tritanopia, plus a colorblind-safe check that flags colors that collapse together. MATCH TO REAL PAINT • Point at a wall or object in a photo to find the closest Sherwin-Williams and Benjamin Moore paint colors. • White-point calibration adjusts for your photo's lighting for closer matches. Suggestions are approximate — always confirm with a physical swatch. BUILD, SAVE & EXPORT • Build palettes by hand or extract them from a photo, and generate perceptual color ramps. • Save and organize palettes in your Library. • Export for design and code: JSON, CSS variables, Tailwind, Android colors.xml, Jetpack Compose, SwiftUI, Adobe .ase, Sketch, and PNG swatch sheets. FREE TO TRY • Color sampling, names, harmonies, and the full contrast checker are always free and unlimited. • Try every Pro feature free — 3 saved palettes, 3 exports, 3 paint matches, 3 colorblind previews, 3 ramps. • One optional purchase unlocks unlimited everything.
