White balance for night scenes
Don’t even try to white balance something like this—use Daylight and leave it at that. In this case, the garish red is true to the eye; gel filters were placed over the up-lights for a special event, so white balancing would not be appropriate anyway. The blue sky is accurate as well. The church is lit by another light source, perhaps sodium vapor lamps. Correcting it would not match my perception, so I’d leave it alone, too, even if it were photographed by itself.
