Have a look here, it shows the same aquarium under different combinations of
tubes.

That's interesting, thanks a lot for the link!

It's difficult to judge colors on-screen -- from what I can see from the
pictures
the pictures in column 2 seem to give the most "natural" color reproduction,
if a bit on the cold side. The 6400K illumination seems to be a bit devoid of
read and yellow tones, as far as I can tell. A bit like the "cold" flourescent
light you get in offices. Personally, I prefer slightly warmer tones.

Cheers,

Michi.
