It seems that colour perception gradually develops a greenish ‘overlay’ as long as one is awake (and gets reset after a night’s sleep).
If you work in an industry where judging colours is important, such as interior decorating or fashion design, this may actually have a significant effect.
Today’s invention is a plugin for Photoshop (or Gimp) which takes this into account and very gradually changes the screen colour balance towards the reddish end throughout a day’s work.
Following a wakeful night, a colour matching test could be arranged at the start of the day to recalibrate the screen so as to provide a personalised, consistent starting point.

The Flux product doesn’t seem to offer any quantitative benefit whatever: certainly nothing that could be tuned to an individual. Or am I getting this wrong?
