ChromaKit samples colors from your photos, reads them out as hex, RGB, and HSL, suggests color harmonies, extracts palettes, checks WCAG contrast, and previews palettes as they appear to people with color vision deficiencies. Everything runs on your device.
Tap "Pick a photo," then press and drag on the image. A magnifier appears above your finger showing the exact pixel being sampled. Release to keep that color — a small ring marks where it came from.
Sampling colors, the WCAG contrast checker, color harmonies, and your recent color history are free. A single one-time purchase — there is no subscription — unlocks saving palettes, the palette library, exporting (JSON, CSS variables, and PNG swatch sheets), and the color blindness preview.
Open the unlock dialog and tap Restore. This re-checks your purchase with the App Store or Google Play and is the right fix after reinstalling or moving to a new device. Make sure you are signed in with the same account you purchased with.
Not directly — ChromaKit stores everything locally and has no cloud sync. You can export a palette as JSON, CSS, or a PNG swatch sheet and share it to yourself, which covers most cases.
No. There are no accounts, no analytics, and no servers. Your photos are read on-device to sample colors and are never uploaded or stored by the app. See the privacy policy for details.
Contrast ratios follow the WCAG 2.1 formula and are exact for the colors you give them. Color names are approximate — they are the nearest match from a reference list, chosen by perceptual distance.

Purchases are handled by the App Store and Google Play, so refunds are requested through them rather than through ChromaKit. On iOS, use reportaproblem.apple.com. On Android, use the Google Play order history in your account.
