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.
