I too just tried it. The default night setting is way too orange, but I adjusted it a bit and then got interrupted by an instant message. About 5 minutes later I went to play with the settings again, the daytime setting (my monitor's default) was blinding! I've been running it for 15 minutes now, the orange tint is barely noticeable. I think I really like this, will try it for a few days.
