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

  1. A target color swatch appears at the top. Your mix starts black beneath it.
  2. Drag the Red, Green, and Blue sliders from 0 to 255. Your mix swatch updates live.
  3. Press Submit when you think your mix matches the target.
  4. 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.
