How to Switch Windows into Grayscale Mode Using f.lux

Microsoft has been adding new features to Windows 10 in every new update. A few months back, they added a feature for turning the PC screen grayscale which is very useful for lowering stress off your eyes as you do the everyday work. We have posted about how you can turn on the grayscale mode by using the color filters in Windows 10. But you do not have to depend on the Windows settings as far as grayscale mode is concerned. You can actually use the third-party tool f.lux to switch your Windows PC into the grayscale mode.

The latest version of the f.lux, a tool that can automatically adjust the PC screen color to match the time of the day or night, provides a grayscale mode. There are two ways of enabling this grayscale mode using f.lux. Before you can use the grayscale mode, ensure that you have installed the latest version of f.lux because the grayscale mode is available only in the version 4.84 and above.

Now you can just right-click on the f.lux notification area icon and select Effects and extra colors → Grayscale. This will turn off any other effects that you were using and switch the grayscale effect on. There is another method of enabling this effect in which you have to open the main window of the f.lux software from where you can click on the menu and select Effects and extra colors → Grayscale just like in the notification area icon.

There seems to be not much difference between the grayscale mode build inside the Windows 10 settings and the grayscale effect of the f.lux software. But in the Windows 10 settings, you will find many extra color settings and also an inverted grayscale mode. No such inverted grayscale effect exists in the f.lux software. However f.lux works even on the earlier Windows versions like Windows 7 and Windows 8.1 and you can enjoy the grayscale mode in your Windows 7 or Windows 8.1 PC using the free f.lux software.
