I only consider pink as gay when the outfit is gay.
Like Hard Gay. And he wears all black. Since when is black a gay colour?
In fact I also think pink can look great. As long as there are darker colours with it and your skin colour matches with it. Then for me it can look incredibly epic.
[I think Hard Gay is awesome btw]
EDIT: BTW I read something somtime a psychologist wrote. It was about colours and the human sexes. And there really is no such thing, that some colours should be naturally preferred by let's say females.
Females usually like pink and red colours. That's because from birth they get confronted with it and they feel like pink is their colour. That's why later in life women think pink is a more girly colour because most women more often like that colour. [And like 100 years ago blue was a girl colour]
They tested it wen they gave young children [boys and girls scrambled] a shirt with a certain colour. Say group A had blue and group B had pink. Then after a few weeks or so, group A thought blue was a better colour and only for group A people and So did group B think the same about pink.
[the same goes btw for toys and such. There isn't something preprogrammed in the brains , which differs in sex and causes your preferation for certain colours or toys or most other things]
So no, wearing pink isn't gay. Unless most people think it is. Considering all the replies so far, pink isn't gay when you wear it.
