Obang: Contrast & Paint Match

Sample any color from a photo, check WCAG/APCA contrast, preview colorblindness, and match to real Sherwin-Williams & Benjamin Moore paint. Free to try.

Sample any color from a photo, check WCAG contrast, and match it to real paint — Obang is a precision color toolkit for designers, developers, and anyone working with color. Everything runs on your device: no account, no tracking.

SAMPLE ANY COLOR • Drag to sample the exact pixel, with a magnifier loupe for precision. • Instant HEX, RGB, HSL, and CMYK, plus a color name and hue family. • Complementary, analogous, and triadic harmonies from any color.

CONTRAST & ACCESSIBILITY • WCAG 2.1 contrast with clear AA / AAA pass or fail. • APCA (the WCAG 3 preview) and ΔE for the full picture. • When a pair fails, get the nearest passing color instantly. • Preview palettes through deuteranopia, protanopia, and tritanopia, plus a colorblind-safe check that flags colors that collapse together.

MATCH REAL PAINT • Find the closest Sherwin-Williams and Benjamin Moore colors to any color. • Calibrate for your photo's lighting for closer matches. • Matches are approximate — always confirm with a physical swatch.

BUILD, SAVE & EXPORT • Build palettes by hand or extract them from a photo, and generate perceptual ramps. • Save and organize palettes in your Library. • Export for design and code: JSON, CSS, Tailwind, Android XML, Jetpack Compose, SwiftUI, Adobe .ase, Sketch, and PNG swatch sheets.

FREE TO TRY • Sampling, names, harmonies, and the full contrast checker are always free. • Try every Pro feature free, then unlock once for unlimited — no subscription.

PRIVATE BY DESIGN No account, no cloud, no tracking. Your photos and palettes never leave your device.
