Effects of four psychological primary colors on anxiety state.
Effects of the four psychological primary colors were assessed by randomly assigning 40 undergraduates (13 male, 27 female) to 4 treatment groups, with each group receiving either red, yellow, green, or blue illumination. Anxiety state was assessed at 5-min. intervals using the State-Trait Anxiety Inventory. The red and yellow groups had significantly higher A-state scores than the blue and green groups, and these values did not change significantly during the 15-min. testing session.
