I have a very clear memory of when I was four and told my mother my favorite color was pink. She said, "Oh no, you can't like pink. Pink is a girl's color."
I can't say this experience had a profound effect on me, although I remember feeling bad any time I saw pink or the color was mentioned. One of my favorite shows at the time was Jellybean Junction. The show's host, Ms. Fran Powell, would sing about how we could be any color jellybean we wanted. "You can be red, blue, or even hot pink!" And I'd think, "Well I can't!" It annoyed me, and I felt that I was getting conflicting messages from the two main authority figures in my life--a parent and the television.
I never did feel any hostility toward girls being able to call any color their favorite (would anyone have told a girl she couldn't like blue?) but I did feel there was something absurd about colors having genders. It seems even more absurd now.
A few years later when Star Wars came out and I started collecting and playing with the action figures my mother called them "dolls for boys". I thought that was a cool description.
