Daytime doesn't use System Prefs Color Profile

  • During the daytime I want the color to be normal. I want to use the color profile I have set in System Preferences > Displays > Color. When F.Lux is on, and I change the System color profile, it shows the correct color for a few seconds, and then the color changes to something else, it's too blue. The profile I have selected doesn't change, but it's clearly not using it. It appears to be using a generic RGB profile, or similar. How can I make it use my profile setting during the daytime?

    This happens on both a Mac Mini running El Capitan and a MacBook Air running High Sierra.


  • Yes we do read the system profile. Can you send us a copy of the .ICC file to look at (support @

  • @herf Sent. Thanks for looking at it.

  • For everyone reading, the profile is a 10-bit calibration table from a Datacolor Spyder.

    We are going to add support to our reader for this, but f.lux is ignoring it in the current build.
