One Significant aspect of the history of gendered colors is that they were adopted first for infants, and gradually applied to older children and eventually adults. This suggests that associating pink with girls and blue for boys has been the earliest lessen in gendered visual culture for million of infants. Babies and toddlers can perceive these colour differences as early as five months and can apply gender stereotypes by the age of two (L. Eliot, Pink Brain, Blue Brain: How small differences grow into troublesome gaps - and what we can do about it, Houghton Miffin Harcourt, Boston, 2009). All children (except the eight percent of boys and one percent of girls who are colour blind) learn pink and blue as gender makers; girls don’t just learn about pink, ad boys don’t just learn about blue. Colour coding may well be the first thing they learn about the rules of gender that govern their own lives.
