Set up redshift for Windows

Redshift is a small program, that changes the color of your display temperature according to the day time. At night the display gets pretty red and feels softer. This way, it feels better to work in the dark. Sadly redshift is only a command line program and we all know how bad the windows command line is (compared to the linux terminal). That’s why I made this tutorial to set up redshift for Windows to use it like a normal program.

First things first. If you don’t care about your privacy and just want a quick solution to getting warm colors at night, there is a program called f.lux which is more user friendly. I recommend redshift, because it is open source, so that you don’t have to worry to much about privacy issues.

Ok, let’s get to it.   Download redshift, take the last stable version, in my case it is 1.91. Then also download this small package.

After that, doubleclick the .reg file to disable gamma limitations (for more information take a look at this page). Extract the folder to where ever you want to store the program, I suggest something like C:\Program Files (x86)\Redshift, and add redshift.ico to the folder.

Also put the icon into the very same folder, you should end up with something like this:

screenshot redshift folder
screenshot redshift folder

Now, we create a shortcut to redshift.exe (right click -> create shortcut). With this shortcut, we can now do everything, we need to do to avoid a command line window. Right click on the shortcut and go to properties. In the tab Shortcut, you will find a text field with the label “Target”. There we can now add parameters to the execution. Here is an example what you can put there:

“C:\Program Files (x86)\redshift-1.9.1-x86_64\redshift.exe” -l 48.208:16.372 -t 6500K:3500K -b 0.8:0.4

Let me break that up for you:

  • “C:\Program Files (x86)\redshift-1.9.1-x86_64\redshift.exe” is the path to your exe file. Make sure it has apostrophes.
  • -l 48.208:16.372 is the longitude and latitude of your location. In this example this would be Vienna. You can find out your location by using openstreetmap. Just press where am i? in the search box, when you are looking at the location you want. And only add 3 digits after the comma, redshift won’t work with more than that.
  • -t 6500K:3500K is the color temperature. the first value is for the day, the second is for the night.
  • -b 0.8:0.4 is the brightness. Once again, first value for day, second for night.

After you found your settings, click on change icon, and search for the icon inside your folder. For a final touch, you can also start the window minimized, so taht you don’t even see the command line.

Now you’re done. Just doubleclick the shortcut, and pin it to your taskbar.

I hope this helps to make the program more useable on Windows. If you like the program, consider donating something to Jon Lund Steffensen. You will find donation buttons on his page.
