My girlfriend, who rides the streetcar everyday to work at OHSU, wants the car to be bright pink, but would mostly likely be happy with bright purple with glitter.
Also, I asked her about the homeless population that rides the streetcar after you guys had a talk about it and she seems to think that not many ride the car (at least when shes one it). Of course there are some, but she has never had a problem with it, and she rides everyday.
