Nighttime white balance.

What white balance do you use for moon illumination.

Daylight. After all, it is lit by the sun, isn't it?

Auto.
White Balance pre settings are warmer or cooler points on the white balance scale.
I always use Auto and if an adjustment is needed I use the eyedroppers in post.
Outdoors Auto is normally correct, except indoors there is often an eyedropper click on white adjustment needed.
