Thanks for all the wonderful comments!
These are virtually straight out of the camera. (save resized, and unsharp masked). Any coloring you see is from the lights and fog. Someone told me "high pressure sodium lights emit a yellow glow." so that's where the yellow toning comes from.
I shot these in RAW format and edited the white balance later. I changed most of them to "incandesent", since it is the closest to how they look normally.
