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.
