There's no number in the center of the circle, just to mess with people's heads and make them think they are colorblind when they stare at it. It's the same principle behind the eye chart with the funky letters.
I assumed it was the one that you only see a number if you are
red/green colour blind. They usually throw that one in to tests so if you're not colour blind, there's usually one where the 'correct' answer is 'no number'.
