Devine la Couleur
Devine la couleur cachée
Part of the picture has lost its color. Move the three dials until it looks right, then submit — the artwork repaints itself in the real color and you see how close you were.
Trouve l'Intrus
Trouve la couleur différente
Every tile is the same color except one. The grid grows and the difference shrinks as you climb.
Mémoire des Couleurs
Mémorise et retrouve la couleur
Study a color, watch it disappear, then rebuild it from memory. The study time gets shorter each level.
Mandela
Lequel est le vrai ?
Two versions of a logo you have seen a thousand times. Only one is the real one.
Scoring
A guess is scored by how far it sits from the real color in perceptual terms — the same CIEDE2000 measure the app uses, not a naive comparison of slider positions. A perfect match is 100. Three stars means you were close on nearly every round.
Keyboard
Every round can be played without a mouse. Tab moves between the dials, the arrow keys turn the focused dial, and Enter submits.
How far the browser goes
The first ten levels of each mode are free here. Everything past them, along with the premium categories, lives in the iPhone app, where your progress and your place on the leaderboards are kept.
