A very interesting article. Based upon this article I will continue to suggest to women to look deeply into my magical blue eyes if the want to improve their cognitive performance.
So blue it was found enhances cognitive performance and red enhances the ability to deal with detail. That in a way correlates to the common perception of blue is for boys and pink is for girls.
This is at odds with Luscher of Luscher color test fame. If I remember correctly ( I am looking at something red right now to enhance my memory) Yellow was the color associated with creativity and thinking outside of the box.
By the way take the Luscher color test, you will be amazed at its accuracy.
