If you want to get gid of the color cast, and if you have some extra cash to invest in your equipment, I suggest getting a speedlight. It's going to cost you some money, but I think once you start to see the results you'll realize the worth of the investment.
I have a speedlight with an umbrella which could be an asset for a shot like this. The light, umbrella, cord, mounting bracket, and tripod are expensive, but you can light the model independently from the metal vapor lights overhead in your shots. You'll probably need a light meter as well, but it might work on TTL with the umbrella--I'm not sure becuase I always use manual flash.
With this setup you can slow the shutter and "drag" it to expose the background and use the aperture and speedlight to light the subject. Because the model would be exposed by flash, she would look normal, but the background would have the warm and interesting orange glow.
Of course, you can always get the Hensel Porty like I plan to if you really want to burn some money.
