Yep, I also do this. It's excellent. Whether it's conditioning, placebo, or an effect of the receptors in the eyes; I'll take it.

There's something that feels good about being in sync with the natural day/night cycle. Cool white in the morning, warmer more dim light at night. I also like the idea of having a "sunrise/sunset" wall for any room that doesn't have proper windows but I've never implemented it.
