My guess about the lighting would be that they are typical street lights. High intensity discharge lamps containing sodium vapor and/or mercury vapor. These gasses often make up the green and orange hues on film due to their lack of a wide spectral range. Almost impossible to filter these types of lights. Corrections can be made, but an image like this REALLY benefits from the odd light colors. This image would not have been as strong in black and white or with a "daylight" colored light source. Great use of unfiltered "non-photographic" lighting. .....end communication
