I really like f.lux, which is an app that automatically adjusts the display's apparent color temperature according to the time of day and location (so that the temperature is in sync with Sun).
How to set the color temperature manually? I.e. without f.lux?
Sometimes I'd like to have "tungsten" (2700 K) colors during the day or morning, which would require fiddling with the location coordinates in f.lux. Sadly, there's no "manual mode" that I'm aware of.
I'm looking for a OS X native / software based solution, that would allow me to set white point below 4500 °K, which is the minimum that Color Calibrator can set. Is this even possible?

This solution requires F.lux to be installed (I assume it's at
/Applications/Flux.app
).Create a text file (let's call it
flux-day-color
) and put it in/usr/local/bin
(usr
is under "Macintosh HD" and may be hidden).In Terminal, run
chmod 755 /usr/local/bin/flux-day-color
Now you can run
flux-day-color 2700
in Terminal (or in another script) to change the day temperature. Note that the script restarts F.lux so you may see the display jump to 6500 K for a split second before applying your requested temperature.It's also possible to schedule this to run at predefined intervals, but that's beyond the scope of this answer (and the question).
If you'd rather have a launchable app that can toggle between 2 temperatures,
Open Terminal and run these commands:
Now you'll see a greater than sign. Paste this:
Wait for the prompt to appear, meaning the file was written. Now the finishing touch:
Now you can launch the new app. You can customize the LOW and HIGH settings to your liking.
