What causes this coloration? (Night photography)


http://ift.tt/2hMyN5W 5DmkIIRokinon 14mm f/2.8ISO 125013 secondsImage #2 is the RAW file, unprocessed, screenshot in Lightroom. You can see decidedly present 'unnatural' colors in the sky.Image #1 has had Clarity and Contrast boosted a little, and the highlights backed off... and obviously the coloration is more pronounced. No color adjustments were done.The lower yellow zone is city light bouncing off a storm headed away, but the purple and the green twinge I just cant figure out. Is it the sensor/processor being thrown off trying to compensate for the auto white balance setting? A broad-scale chromatic aberration from the lens? via /r/photography http://ift.tt/2urTJRA
