I jest, I jest. I'm honestly not sure where the roots developed from but pink probably came to fruition as being assosciated to girls in ancient European civilisations as a form of faded red due to the lack of other vibrantly colored dyes cultures which eastern parts of the globe likely posessed hence the wider colors used to represent womens attire in those regions.
As for the blue, is it possible that it arose either from the grey garments of men, or the steel of their blades, or most likely; the color of where they made their livelihood. The sea.
I would imagine the latter makes much more sense as it was only men who held the profession of fishermen in many cultures so the sea was very much the domain of men, and as such the color of blue would become assosciated.
It used to be the opposite before Hitler assigned homosexuals to wear pink triangles. Girls used to be associated with light blue, to be associated with purity and the virgin Mary. Boys with pink, because it was a paler shade of red.
