Combination of colors is the study of hues as a determinant of human nature. Color influences impressions hat are not obvious, such as the aroma of a drink. Another way in which colors have been used to impact actions was, in 2000, when the city of Glasgow installed blue street lights in certain areas which resulted in a cut down of the crime rate. Color can indeed impact an individual, however it is important to remember that these developments differ between society. The factors such as gender, age, and culture can impact how a person perceives color. For example, males say that red colored costumes made women seem more attractive, while women answered that the color of a male’s dress did not affect his look.
