In theory, colors should be completely genderless. In marketing and consumer perception, colors are 100% gender-specific. For certain products, there are color breakdowns and color combinations that 'only' work (and 'never' work) for men, women, boys, and girls. For example, if you Google "Pink Jordans", I guarantee you that 95%+ of the results are going to be for girls, women, and kids.
Retailers will consistently decline to stock certain products in gender-specific colors, which then leads to manufacturers and producers creating products in gender-neutral colors. In fact (and this isn't a secret, more of a marketing thing), if you want to sell a product in pink, late September and all of October is the best time to do it. Very very very few retailers can get away with declining to stock pink products/Pink Ribbon products during breast cancer awareness month.
