DeltaE - Colour Guessing Game

deltaE is a color perception game that tests how well you can remember and recreate colors. Each round, you're shown a color for a few seconds — then it disappears. Using hue, saturation, and brightness sliders, recreate the color as accurately as possible before the timer runs out. Your score is calculated using CIEDE2000, the gold standard color difference formula used in professional color science. Play 5 rounds and see how sharp your color perception and memory really are.
