windows 10 base color yellow

  • I have been using f.lux for several months now and regularly deactivate the function until sunrise. Yesterday my coloration retained the yellow night setting and has not reverted. I have uninstalled and reinstalled the software. I have updated my video card drivers. I have attempted to adjust my colors via color management. Nothing has altered the base yellow color. I have manually adjusted my monitor settings, and that menu appears in crisp white, as such I am fairly certain this issue is software in nature.

    I am currently running windows 10 x64, with Inter i5-4570 CPU @ 3.2 ghz, 8 gigs ram, GeForce GTX 760 to an ACER P216HL.

    I appreciate the function of f.lux, but at this point it has rendered my computer unusable for gaming as it makes me effectively color blind in many situations. I greatly appreciate any knowledge you can offer that will allow my to use my computer again.

  • Disable Night Light in Windows 10.

  • Thank you for the suggestion, nightlingh is and has been off.

  • Sorry I did not think of this sooner. Below is a picture of my monitor settings menu showing with crisp blues and white, and the background is yellow as displayed with the current settings.


  • Yep, no software can control the monitor's OSD color.

    Anyway, is f.lux.exe still running? Check Task Manager.

  • @TwoCables

    I have uninstalled f.lux and restarted my PC several times.

    I know, but, check Task Manager to see if f.lux.exe (the executable) is running. This sometimes happens.

  • I double checked Process, App History, Startup, Details, and Services.

  • Then I am personally out of ideas. I'm sure @herf or @lorna will be able to help though.

    Sometimes system updates can mess with video drivers and quietly downgrade them, in which case f.lux can run into trouble.

    If you can look for available updates / post your driver information that would be really helpful.

    It sounds like you've done just about all of the right things. Your picture looks really bright yellow, where most f.lux settings are orange into red, so the first thing I'm wondering is whether there's something else going on, like if there might be any other additional software that you or someone else might have installed that affects monitor color.

    If there's no other software running and you have updated video drivers, installing a monitor profile would be your best bet to clear out the tint:

    If f.lux isn't running in your task manager and you've uninstalled it, something outside of f.lux is going on (like a video driver grabbed onto your night time f.lux profile and won't let go). Installing a new monitor profile should help.

  • Thank you for the advice. According to the ACER my drivers are P216HL and can be downloaded at @ SERIES&Step3=P216HL&OS=ALL&LC=en&BC=ACER&SC=PA_6#_ga=2.59545517.1430487269.1519276093-1869965474.1519276093.

    I followed the instructions provided above, How to get the correct color profile for your monitor and How to install the correct color profile for your monitor and learned that I already had that specific color profile. So I removed that profile and added it again. No results unfortunately.

    Hi Chris - a few ideas:

    1. Can you change the resolution of your display, to see if the video driver has made some adjustments to your monitor? You can change it back right after. If this helps, we'd want to look at the OSD to see if the Acer monitor has learned some settings that need to be reset.

    2. Can you also try reinstalling f.lux and see what happens if you move the sliders around in the interface?

  • @herf I changed resolution. no change to color. I reinstalled flux. All adjustments to color are still made from the base yellow.

    Can you also take a look at the "color management" control panel and see if there may be a bad profile installed?
    After that try "calibrate display color" to see if it can be fixed that way.

    As Lorna said, canary yellow is not a color tone f.lux ever makes, so I think we are looking for some other software/interaction that is causing the problem.

  • That photo looks like 1900K to me. It's just not the best photo or monitor color accuracy. Seriously, make your monitor bright and then switch back and forth between 6500K and 1900K very quickly while you're staring at the photo. You'll see.

  • f.lux team

    @TwoCables that photo has a reference white, and so you can see that the yellow is basically (1, 1, 0), which isn't anywhere close to 1900K. Something in the system has knocked out the blue channel (almost) entirely, and that's not what f.lux will do at any color temperature setting.

  • f.lux team

    I would check color settings in the OSD.
    And also, how is the monitor connected? (The older 15-pin d-sub connectors occasionally could have a knocked-out channel that looked like this.)

  • insert hysterical laughter here So herf, the cable was loose. What are the chances of my messing f.lux at the exact time that the cable loosens enough to make my screen go urin yellow. Thank you for your time and knowledge :)

    @Chris-Martin that's amazing... glad we could help.
