I would guess that it's not even color-correcting really; I've taken long-exposure photos at nighttime that came out as perfectly normal green trees against a mostly-perfectly-normal blue sky (only mostly normal, because it did have stars visible in it), and they weren't particularly color-corrected. But the eye cells that see color are less sensitive to dim light than the full-spectrum ones, so what's happening is that we're seeing less of the color than we'd expect to.
