iPhone and iPad
The ColorArchive iOS app is free and needs no account. It puts all 5,446 colors on your phone — browse, search, copy, and save them, online or off.
Free · iOS 17.0 or later · Graphics & Design
The whole library ships inside the app. The colors are generated algorithmically, not fetched, so browsing works with no connection at all.
Type a word like “ocean” or “autumn” and semantic search expands it into the matching color families.
Long-press a card in the grid to copy HEX, RGB or HSL without opening it first.
Favorites are stored on device. Contrast checking, colorblind preview and harmony tools are in the app too.
If you came for one of these, use the site instead — the app does not have them.
