Haishoku

Haishoku collects the 159 colours and 348 combinations gathered by the Japanese artist and colour researcher Sanzo Wada in the 1930s, and binds them as a flipbook you turn with real page curls.

• Browse by colour or by numbered combination, with thumb tabs on the page edge for quick jumps.
• Find the nearest Wada colour to anything you pick, photograph or point the camera at.
• Export palettes as Procreate swatches, Adobe .ase files, image cards, CSS, SwiftUI, Tailwind or JSON.
• Check contrast for every pair, save favourites, and get a Palette of the Day widget.

It works offline and collects no data. Colour values come from the open dictionary-of-colour-combinations dataset (MIT licence).
