Until the 20th century, pink was a boy's color and blue and white was girls. You cannot be for real.
As usual it is a bit more complicated than that:
Has Pink Always Been a “Girly” Color?
Historically white was the color for all kids. Easier to clean and bleach.
In the latter 19th century pastels came out for babies. And there was no color preference. All pastels were chosen. But in the early 20th century a fashion decision was made:
" In 1918 the trade publication
Earnshaw’s Infants’ Department claimed the “generally accepted rule is pink 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.” Additionally, a 1927 issue of
Time noted that large-scale department stores in Boston, Chicago, and New York suggested pink for boys. This trend of pink for boys was not as overwhelming as our current color-sex designation, however."
The association with boys in blue began during the baby boom when babies were also dressed to reflect their parents:
The baby boomers in the 1940s were the first to be dressed in the sex-specific clothing that Americans are familiar with today. Boys and girls were dressed like miniature men and women instead of uniformly in children’s dresses. Pink became the girls’ color, blue the boys’.
By the way, if you see some older portraits of children you will often see toddlers in dresses, regardless of sex. Boys and girls both wore dresses. If they were still wearing diapers it allowed much easier access to the garment. That is why boys getting their first pair of pants used to be an event.
