I occasionally take panoramic city photos and I've noticed that certain sections of the cities have a lot of different coloured lights.
What causes these different lights? Some of these appear to be 'coloured' lights (the green and red for example) but there's a lot of purple and orange and white lights which 'look' white when you view them with the naked eye.
I've previously had issues like this and I've found that correcting using white balancing works wonders, however, I believe all these lights are of different temperatures so I cannot balance them all.
Is there any way to fix this?
Below is a snip of a picture from one of the shots:
