Moonlight - Blue or White?

From what I've heard some people say (at least on the plant forums) is that they prefer the white light because moonlight would really only look blue in deeper SW. The light would still be white-ish in most fw systems. *shrug* I like both, but I think I prefered the white look when I tried some little lights over the tank.

But blue is good, too I have a 15w incandescent blue bulb that I sometimes stick over the glasstop on the 55g and it casts a really nice effect. I think it's just personal preference.

Here is a link that talks about the best colour light for that 'natural' moonlight colour.
