Blue for girls and pink for boys

From Allen Abel and Madeleine Czigler’s “Boys, despair and aristocrats” (National Post: 24 June 2008):

Blue clothing for girls and pink for boys — and not the reverse — was the custom in North America for much of the 20th century. “The reason,” according to the Ladies Home Journal in 1918, “is that pink being a more decided and stronger colour is more suitable for the boy, while blue, which is more delicate and dainty, is prettier for the girl.” Not until the 1950s did the reverse become entrenched.
