Name the ink colour, not the word. A colour word is printed in a colour that often disagrees with it, and you answer as fast as you can.

Half the words match their ink. Half do not.

Say the colour, not the word.

A colour word appears in the middle. Tap the button for the colour of the ink, not the word you read. You have a couple of seconds per word, so answer as fast as you can without guessing.

How to play

A colour word appears. Answer with the colour it is printed in. If the word RED is printed in blue, the answer is blue.

Half the words in a round are printed in the colour they name. The other half are not. Both halves ask for the same colours the same number of times, so the two can be compared fairly.

Each word has a time limit. A word you do not answer in time counts as missed and is left out of the timing.

Use the number keys 1 to 4, or Tab and Enter, to answer. The buttons stay in the same order all round.

At the end you see how much slower you were on the words that disagreed. That gap is the point of the task.
