Developing Color Preferences Korean artist Jeong Mee Yoon is obsessed with pink and blue. If light matters for the development of vision, maybe newborns that spend a lot of time in a pink environment develop better pink detecting eye-to-brain wiring than children surrounded by blue. If early exposure to lots of pink or lots of blue conditions the infant visual system to the point where a physiological preference develops, then the effect is much delayed Love of the color pink never hurt anyone, but the same molecule that leads some adults to become addicted to harmful drugs, might just be involved in causing some girls to seek out all things pink. Each of the positive responses might stimulate the child’s dopamine system, causing her to continue to seek out pink things. Fundamental reward systems include food, physical comfort, sex, and emotional well-being.
