Pink's been cool for a long time. I recall stopping in at my downstairs' neighbor back in San Diego. He collects guitars and he had some old hard core biker sitting on his sofa seriously bummed out. Apparently said biker was standing at a stop light earlier next to some little kid with a rad pink bicycle. Being "Old School", this biker was trying to give the kid a hard time about having a PINK bike. The criticism ran off the kid like water off a duck's back. He just didn't have the old prejudices about pink, his bike was COOL. The old biker was seriously shook up by the whole cultural encounter. He was talking to himself for quite awhile about the whole thing.
PS The RAF had pink Spitfires that they flew at dawn and sunset.
