Feature request : set dawn light colour by RGB code

[GoogleCodeExporter]

Hi,

Knowing that blue light (= about 460-480nm wavelength) seems to best "wake up" 
the brain in the morning (see for instance 
https://clinicaltrials.gov/ct2/show/NCT01557595), wanted to set the fake dawn 
colour to that.

Using a converter, I found that 470nm is roughly [0,153,255](dec) or 
[00,00,FF](hex).

However, the circular colour-picker in Fake Dawn cannot take numeric values, 
only what colour you tap on, which is highly imprecise (and even impossible in 
case you're colourblind).

An RGB field along with the colour-picker would be a nice addition.

And why not use 470nm-blue as the default colour ?
