$4.99 · Designed for iPad. Not verified for macOS.
Identify, compare and create colors with confidence. Live and photo analysis, 206 references, palettes, harmonies and accessibility tools—all on device.
What Color? is the professional toolkit for identifying, studying and creating colors on iPhone and iPad.
IDENTIFY ANY COLOR
Point the camera at a surface or choose a photo. Tap the area you care about to see the nearest generic reference, the exact sampled HEX and RGB values, and a confidence indicator. Zoom in, pause live detection, adjust the sampling area and hear the color name spoken aloud.
ANALYZE YOUR PHOTOS
Move the reticle precisely, open an image full screen, magnify fine details and automatically extract a dominant palette. Share values or save a sample to your library.
CONVERT AND COMPARE
Work with HEX, RGB, HSL, Lab and OKLCH. Adjust RGB channels numerically or by percentage, copy CSS, SwiftUI and UIKit snippets, compare two colors with CIEDE2000, and check contrast against WCAG AA and AAA criteria.
BUILD BETTER PALETTES
Blend two colors using multiple models. Generate complementary, analogous, triadic, tetradic and monochromatic harmonies, then save your work as reusable palettes.
DESIGN FOR ACCESSIBILITY
Simulate protanopia, deuteranopia, tritanopia and achromatopsia. The accessibility lab suggests more distinguishable companions and previews how choices appear across different vision profiles.
206 REFERENCES TO EXPLORE
Browse and search a catalog of original generic color references. Open any entry to inspect advanced values, hear its name and save it with one tap.
PRIVATE BY DESIGN
No account, cloud, advertising or tracking. Photos, colors, notes and palettes stay on your device, and every feature works offline.
Pay once. No subscription and no in-app purchases.
Please note: detected color can vary with lighting, camera, display and surface characteristics. Always use calibrated instruments for color-critical work.

• Much faster photo analysis on high-resolution images
• Save failures are now reported instead of silently discarded
