In 1918, an article from a trade publication called Earnshaw’s Infants’ Department, declaredthat, since it was derived from red, “Pink is for the boys, and blue for the girls. The reason is that pink, being a more decided and stronger color, is more suitable for the boy, while blue, which is more delicate and dainty, is prettier for the girl.”

It's pretty interesting, I haven't heard it before.
