I hear you, that was a big issue for me as well. It's not just a girl thing though. My husband ordered a new green Rambouillet before I got my Rambouillet. They had one in stock his size in the current blue, but he didn't like that shade of blue for himself and opted to wait for the new green ones they were going to have in a few months. So he will wait patiently for months now. Meanwhile, I just lOVED that cerulean blue shade and they did happen to have my size frame in stock as well, so I wound up getting the blue one right away! I was just lucky.
As to your dilemma....
Try accessorizing! -Handlebar tape?, hand grips?, saddle, bike bags, helmet?, gloves?, pedal straps?, bells?, colored sidewalls?, stickers?, playing cards in the spokes?, streamers?.... If all else fails, just buy some totally happenin' biking duds and make a statement with what you wear while biking.
