How to play Color Guesser

Every color on a screen has a code, like #FF0000 for red. The game shows you a code and asks which color matches it. Tap the right one before the timer runs out. You can also press the number keys 1 to 6.

A hex code has six characters after the #. The first two are red, the next two are green and the last two are blue. 00 means none of that color and FF means all of it. So #00FF00 is pure green.

Three modes

Scoring

A right answer earns 100 points, plus up to 100 more for answering quickly. Every 3 right answers in a row raises your multiplier by one, up to times 4. A wrong answer sets the multiplier back to 1. After a miss, the game shows the right code and how close your pick was.
