Thirteenth International Conference on Design Principles & Practices

Abstract

There is extensive research carried out about colour affect , however, very few studies to date have examined colour psychology in “colour-blind” observers. This study aims to delve into the psycho-physical impact, if any, that colour has on the “colour-blind” population. The study re-defines the term “colour-blind”. It also focuses on differentiating between light and colour to have a better understanding of the topic. The findings showed that colours are the result of reflected light that hit the retina. Our brain interprets these wavelengths to create a physical and sensory experience of colour. In colour-blind individuals, due to the absence of functional cone cells the wavelengths are not detected which in turn does not create an electrical impulse in the brain to stimulate a hormonal or biochemical process in the body.
