Hehe! Yes, it's definitely amusing how colors often continue to be so closely associated with gender identities despite being so arbitrary. But these days, those color schemes are starting to be seen as even more "outdated" rather than just somewhat old-fashioned.

Although well-intending organizations in the past tried making things simpler by restricting the division of play and color based on gender, people who like blue or pink beyond their prescribed nominal identity still make appearances in various forms - resulting in rumors floating everywhere that blue has increasingly been repurposed for boys after initially being used by girls even for western conservative households rather than patriarchy leading attraction towards blues.

Here's a potential joke based on that last idea: Why did the boy baby start becoming fussy when he was dressed all in purple? Because his parents forgot that according to a random-assigned rule he is only allowed wear one dominant color scheme, little John had ended up confusing himself trying to figuring out whether he should join the girls' team (pink) or boys'' team (blue), go figure!
