Question

Why is it difficult for you mind to register a word such as " Green, Blue, Red, Purple, ect. " if the word is written in a different color such as " Green is written in Purple ink, Blue is written in Red ink, Red is written in Green ink, and Purple is written in Blue ink "

Answer 1

Because your reactions and brain are confused as to which it should react to first, the colour or the written colour.

Answer 2

Because we aren't used to that and because the word blue means the color blue so it should be blue but instead it's red.
