How fast can you say all the colours? Time yourselves and have a competition!

This is called the Stroop Effect and was discovered by John Ridley Stroop in the 1930s. It demonstrates interference between the different information that your brain is processing - what the words say and the colour of the words themselves. This confusion slows down the speed at which you can say all the colours.
