Color psychology is the study of color as a determinant of human behavior. Examples include quantification of individual color preferences[1] and investigating the relationship between shirt color and match outcome in English football.[2] However, the interface between color and environmental stimuli is a highly complex interface and one which is open to the influence of a large number of factors. In addition, there are a number of key reasons why the principle of caveat emptor should prevail in regard to color psychology, especially in regard to information about colour psychology found in mainstream media and popular culture.[3]
