Haishoku
Find color in the world.
Free · In‑App Purchases
A daily ritual rooted in a hundred years of color theory. Find today's three colors in the world. Haishoku+ now available — no ads, see past colors.
Haishoku (配色) is Japanese for "color combination." Pronounced hai-SHO-koo. Here, a daily camera-based color game.
Each morning, three colors are released. Use your phone's camera to find them in the world around you — one at a time, no rush. The app reads color in real time and tells you how close your match is.
The day's three colors are drawn from a hundred years of color theory — Sanzo Wada, Johannes Itten, Albert Munsell, Le Corbusier — beginning with Wada's 1933 Dictionary of Colour Combinations. The world is your studio.
— Open the app and play. No account needed for the daily game, nothing to set up.
— Your camera stays on your device. The camera samples color frame by frame; we don't capture, save, or upload any photos.
— Color-vision aware. During first launch, you can tell Haishoku how you see color — standard, protanopia, deuteranopia, or tritanopia — and the app filters its daily palette to triads distinguishable in your perceived color space. Change it any time in Settings.
— Optional daily reminder. One notification a day, at the time you choose, only if you opt in. Off by default.
— Free to play, with light ads. Haishoku+ is an optional subscription that removes the ads and adds an archive of recent puzzles you can play — go back and play a day you missed, or replay one to sharpen your match — plus a quiet stats overview (days played, streak, tier distribution, average match accuracy) and cross-device sync of your match history. The daily game is complete and free — Haishoku+ adds depth, it doesn't gate the core.
— Sign-in is required for Haishoku+ on iPhone, with Apple or Google. Your subscription is tied to your account and follows you across your devices. The free daily game never asks for sign-in.
