It is, everyone forgot that guys saying its manly was a joke to begin with.
Hey, colors don't have an opinion on the matter - they don't care who uses them or likes them. It's us who decided that women and men needed segregation when it comes to colors. Now, I'm not saying a boy should have a bright pink room, but IMO it doesn't look good as a girl's room either; pink is just too bright to fill an entire room with it. If you're going to categorize colors, do it in ways that make sense (like most colors already are).
