How to play
Study the target color and prompt, then tune Hue, Saturation, and Brightness until your live doodle visually matches the target.
What is HSB?
HSB separates color into hue angle, saturation intensity, and brightness value. It is easier to reason about than raw hex codes.
How scoring works
After you submit, Color Challenge compares your guess with the target using perceptual color distance and shows accuracy, ΔE, and H/S/B breakdowns.
