I don't think that you should paint it yellow because it is becoming too common of a color.....go for something a little more different.....if you want to stand out maybe a baby blue, that would look really nice...but it all depends on your taste. But why would you go and get another car when you really don't know anything about cars? Not trying to be mean, but slow down a bit and learn a little before you jump right into things. Also, you should do the things you want to do to your car, not what other people say you should do......if other people don't like it, who cares....they are not driving your car right??
By the way welcome.
