Tom, I don't know about the blue numbers maybe T or S will know.
I thought it looked overall blue to but then that is what it looks like when I look up at it.
I copied and desat a little and adjusted the curves a bit more. Does it look better?
often times with my stuff, i have difficulty distinguishing 'better' from 'just different'. carefully avoiding your direct question, i'll just say that the moon is a bit brighter here. flipping back and forth, it looks as though a bluish film was removed from it...
