For daytime hours I would like something approximating the suns spectral output. Something like a black body at around 5800K. Lots of blue but pretty flat in the visual spectrum.

For the evening I would prefer more of a wood fire or candle light spectrum. That seems to help with people's sleep cycle. Something with a black body temp of about 1500 K. Or cool incandescent if you are reading; around 2400K. Majority red spectrum.
