## What is Obang?

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.
