I suspect they vary, a little. But perception also varies - a lot. It took me only a very short while to get used to having f.lux on my computer, for example. If I do an abrupt transition, the thing looks absurdly pink/orange. With a gradual transition, I don't notice it at all. As I became accustomed, I pushed the temp further - 4500 K for daytime, right down to 2100 K at night. (I don't do colour-sensitive stuff on my computer, obviously! Mainly text-based stuff.) Wikipedia tells me that 4500 is between moonlight and horizon daylight, and 2100 is just a little cooler than a candle flame or sunset.

I'm in favour of less blue lighting - it should be better for sleep.
