About ColorFlex

ColorFlex is a free color guessing game built for the generation that scrolls Sephora hauls, sneaker drops, and album covers all day. We test how well you can match the colors you see every day — and we make it social.

What we built

Every round shows a trending product and asks you to match its dominant color using an HSB picker. You score 0–100 per round based on how close your guess is. Five rounds per game, three game modes (Solo, Daily, Multiplayer), 13 themed categories — everything in a browser, no download, no signup.

Why HSB?

ColorFlex grades in HSB (hue, saturation, brightness) instead of RGB or hex because HSB matches how human visual cortex represents color. A 10-point HSB miss actually looks meaningfully different to your eye — the score reflects perception, not channel math. Read the HSB guide.

No ads, no signup

We don't run ads, we don't require an account, and we don't sell data. Daily scores use a browser-local identifier; if you want to keep a streak, don't clear your cookies. That's the only catch.
