Slide Red, Green, and Blue bars to recreate a target color shade from scratch and score your accuracy out of 100.
How to play Color Match
A target color swatch appears at the top. Your mix starts black beneath it.
Drag the Red, Green, and Blue sliders from 0 to 255. Your mix swatch updates live.
Press Submit when you think your mix matches the target.
Your score is based on how close your RGB mix is to the target — a perfect match is 100.
Score uses Euclidean distance in RGB space: dist = √((r−tr)² + (g−tg)² + (b−tb)²), then score = max(0, round(100 × (1 − dist / (255 × √3)))). A perfect match scores 100; opposite corners of the color cube score 0. Every submission receives a score — there is no lose condition.
