>Pink used to be a boy's color. //
Which shows nothing. The natural allure might be for girls [in general] to go with pink, and the use of pink for boys (is/was it something to do with hunting?) might have been pure social conditioning.
Aside: Are their examples of paintings showing boys in pink? The only historical "pink" I know of is "hunting pinks" which are bright-red.
I imagine we're only talking "aristocratic boys", as red dyes were expensive and most boys through history will have had natural coloured clothing, I imagine.
My eldest boy used to adore his pink handbag, fwiw. That's a very limited data point, however.
Edit: found https://en.m.wikipedia.org/wiki/List_of_historical_sources_f... it does strike me these are selections to prove the point, ie poor statistics. Also there might be errors (blue for a boy, and pink for a boy - sounds most likely to be an error). Also that a lot of the pink for a boy quotes are for babies; seems like what mother's choose for babies is different to what children/juveniles/adults will choose for themselves.
Interesting though.
