The Effect of Color on Conscious and Unconscious Cognition
Color is an important part of human perception. Many everyday objects have been
designed to convey a message through color. The way that colors effects psychological
processing has not been fully explained. In particular, past studies on the effect of color
on cognitive tasks have presented contradicting results (Mehta & Zhu, 2009). These
studies have often only assessed two of the three primary colors at a time and still had
contradicting results. Most studies focus on comparing red to either blue or green. The
results from the studies have been a mix with some of the studies showing red to enhance
cognitive task performance over blue or green and the other studies showing the opposite
affect.
