The difference, I would bet, is mainly because of the differences between the retina and a sensor in low light. The color was not seen by you because when it is fairly dark, the eye is basically a monocolor sensor. The cone cells are not working well and you see with the rod cells, that are only B&W, so to speak. Like a dog. But the camera sensor can sense the color and it will show up. Like taking moonbow photos of a waterfall. It will appear to your eye to have not color and not be worth taking, but to the camera, either digital or film, it will have color, just like a "real" rainbow. No matter, the shot is just magical to look at. It was a nice find, even if you did not know what you were looking at at the time. An experienced eye saw the patterns and textures and the sensor saw the color.
