Think that way, why most of the girls like the flowers? Why they are happy when someone gives a rose to them? I think it is not in our nature we learn some certain likes from environment and like the other people we start to like these flowers, life teaches us that flowers are good and make us happy. It is like learned behavior I guess. I think your question is like that for some aspect. Even a new babygirl is weared in these colors. They open their eyes and see pink and red. Morever, maybe we find them more lovely they inspire good feelings inside us, maybe it is a issue related to not only the learned behaviors and but also some biological thing. Good question :) Good luck!

Excellent question... I've always wondered about that.

maybe you should asked "why girls like ... colors?but boys do not like " because actually , girls can always dressed in those fresh colors ,but its a little strange for boys ,its my opinion (*^__^*) ，but i do not mean boys can not dressed in those colors

oh, sorry. That's are not my favourite colour.

because all girls are princess :)they all have a princess dearm:)
