Color Reading

Below you find a number of words written in different colors. Try to name the colors you see as fast as possible. This means that you should say the names of the colors in which the words are written, and not read the words themselves.

black      blue      green     
orange      pink      yellow     
purple      red      black      white

You probably noticed that it is rather tough to say the names of the colors very fast, since your brain is also reading the text, which is almost unavoidable...
