2013 Reprint of 1950 Edition. Full facsimile of the original edition, not reproduced with Optical Recognition Software. American writer Faber Birren devoted his life to color and it's effects on human life. After writing around 25 texts on the topic, it would be safe to say his work is considered highly among color experts and psychologists around the world. Birren's work has a strong focus on linking how humans perceive colors to how it makes them react. He writes, Good smelling colors are pink, lilac, orchid, cool green, aqua blue. Birren explores the work of several physicians, scientists and doctors, mainly the German psychoanalyst and physician Felix Deutsch, whose findings throw important light not only on medical practice with references to color but on the whole psychology of color. Birren states that if a person prefers warmer colors such as hues of red and oranges, they are likely to me more aware of their social environment. He labels these as warm color dominant subjects. O
