Read through the following list but DO NOT say what the words spell instead say the COLOUR the word is written in.
After long struggle read the complete list??
This is a classic example of a left brain - right brain conflict. The right side identifies the colour but you must first disregard the word which is being provided courtesy of the left side(which is responsible for character recognition). This was the reason which slow you down a bit having to sort out these two conflicting bits of information.
