Hexercise

Can you train your eye to remember an exact colour?

Hexercise challenges you to memorise a target hue, then recreate it as accurately as possible. No multiple choice. No hints. Just your memory and a set of sliders.

--- HOW IT WORKS --- A colour appears on screen for 3 seconds. It disappears. You reconstruct it from memory using hue, saturation, and lightness controls. Your score (0-100) reflects how close you got. Simple to learn, genuinely difficult to master.

--- THREE WAYS TO PLAY ---

SOLO PLAY Endless rounds to sharpen your colour perception. Every score is saved so you can track your progress over time. Great for a quick daily warm-up.

DAILY CHALLENGE One set of colours, the same for every player, every day. Submit your score to the global leaderboard and see where your colour memory ranks worldwide. A new challenge arrives each day.

VERSUS MODE Go head-to-head against a real opponent or a ghost player. Best of 4 rounds - both players see the same colour, best accuracy wins. If scores are level after 4 rounds, a sudden-death 5th round decides it.

--- DESIGNED FOR PEOPLE WHO CARE ABOUT COLOUR --- Whether you're a designer, artist, developer, or just someone who's always been oddly confident about knowing a colour - Hexercise will humble and improve you in equal measure.
