A hundred years ago, pink wasn’t girly and blue wasn’t masculine. In fact, according to some, it was the opposite.
A 1918 trade magazine for baby clothes explained authoritatively: “The generally accepted rule is pink for the boy and blue for the girl. 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.”
But since about World War II, the tradition switched and pink became the color just for girls.
I simply cannot picture a little boy with his pretty pink backpack while his sister’s is blue. Guess I’m a child of my times.
