dialed-gg

Dialed GG is a free browser gaming hub built around a color memory test. Each run gives you five rounds: you see a color, hold it in your head, then rebuild it with three HSB sliders. Every guess is graded with the CIELAB Delta E 2000 perceptual difference formula, so the gap between what you remember and what you produce becomes your score.

A daily challenge gives everyone on Earth the same five colors, and the site also hosts twelve more free games: music quizzes, word ladders, a 3D globe and estimation puzzles. No signup, no ads, no paywall.
