What you just experienced was left-brain / right-brain conflict. Your right brain saw the color but your left brain insisted that you say the word. The conflict made this activity slow and often frustrating. You have been forced to be this way because it is how you learned how to read. You have read this way for many years and it is ingrained in you. Your left brain first wanted to say the word, but then it analyzed the color. Meanwhile, your right brain knew all along the colour, but was dominated the whole time by the left brain trying to do a simple right brain job.
