How to play

Every day there's one color, the same for everyone (it flips at midnight UTC). Look at the swatch and type its 6-digit hex code — you get 6 guesses. After each guess, every digit gets a hint:

✓ green — that digit is exact
↑ / ↓ pink — within 1 of the target digit, arrow shows the direction
↑↑ / ↓↓ grey — further off; the target digit is higher / lower

Remember hex digits run 0–9 then a–f, and the pairs are RR GG BB — so the first two digits are how red it is, and #ff2e88 is a lot of red, a little green, and a generous helping of blue. Finished the daily? Practice mode deals unlimited random colors.

Why this makes you better at CSS

Reading hex colors is an actual skill: once you can eyeball that #2a9d8f is a muted teal without a picker, code reviews and quick CSS edits get faster. The per-channel arrows train exactly that mapping — channel by channel, digit by digit.
