A few years ago I was exactly like you. Even now, I still very much agree with you in 'spirit', and perhaps in the VERY long term (1000-10000+ years) evolution may fix the 'bug' which stops your argument from making perfect sense.
This 'bug' is that blue light affects melatonin production (decreases it, so it's harder to get to sleep). This isn't something you can get around. Subjectively, it could also be said that orangey hues (even more red than incandescent!) look 'cosier' and are a nice contrast to the day's blue light. Due to the nature of qualia, that's almost impossible to disprove. Heck, even green and blue illumination is a nice change occasionally.
Yours though is the first comment I've read in my life that even goes in this direction though, so I think that's awesome in itself. You might be interested in my post at CandlePowerForums which tried to find out what colour temperature is subjectively closest to pure white:
