How Colour Match Works (and the Maths)

Colour Match is a chance game with information. One of six labelled swatches is chosen at random. You tap until you find it. This is entertainment, not a stake or a prize.

How Colour Match works here

• The six colours are Red, Blue, Green, Yellow, Purple, Orange. Each has a name on the chip — you are not guessing unnamed hues.
• The target is picked uniformly at the start of the round.
• A wrong colour stays marked. You never need to try it again.
• Fewer guesses is better. Ratings run from “Perfect Match” (1) to “Eventually” (6).

How to play Colour Match

• Open Colour Match. Tap a colour.
• If it is wrong, pick another remaining colour.
• Stop when the chosen colour is found.

Strategy that matches this board

• There is no colour-theory shortcut. The target is random.
• If you never repeat a miss, the number of guesses is uniformly 1 through 6. The expected value is (1+2+3+4+5+6)/6 = 3.5.
• Repeating a marked colour only wastes a turn. The UI already prevents that usefulness by leaving misses marked.

Personal best

Lowest guess count on this device is stored locally. A first-try win is luck, not skill.

Questions about this implementation

Do remaining colours stay equally likely?

Yes. After a miss, the target is equally likely among the colours you have not tried.

Is this colour-blind accessible?

Each chip is labelled with its name as well as a fill. That is the main alternative to hue alone.
