Does anyone know a polar night theme alternative without the bluish hightlight? I like the closing icons very much, but the blue is a killer for night work.

There are a few alternatives to the polar night theme:

Alternatively, you could also replace the theme colors (warning: can be lengthy and boring process). These are defined by hex strings such as #8EC3EB. So you can search

To do this a while ago I created a rough script to find them in files - it can be found here and can be used like this:

find /home/wilf/Downloads/polar-night-master/ -type f -exec /path/to/scriptfolder/grephexcolourcode {} \; | sort -u

Where /home/wilf/Downloads/polar-night-master/ is where the theme files are located, and /path/to/scriptfolder/grephexcolourcode is where the script is located (or just grephexcolourcode if it is in the $PATH).

You can then replace the colours using sed or similar - e.g:

sed -i 's/#8EC3EB/#EB8E8E/g' /path/to/theme/file

Or using find and replace in a program such as Gedit, BLuefish etc


An alternative is to use a normal dark theme (usually blueish - I use Arc-Darker), and then on top of that at night use something like redshift-gtk to make it more bearable at night. You can launch it with a command similar too:

redshift-gtk -l 55.7:12.6 -t 5700:3600 -g 0.8 -m randr -v

It will automatically change to be more red at night. This covers the entire screen, so works too with light areas themes can't effect easily (e.g. most webpages, documents etc) but due to blue light being filtered blue things will turn dark so not ideal for graphics work or some themes.

  • I hope someone creates a red or orange version of polar night. – empedokles Sep 15 '15 at 18:08
  • @empedokles - I guess you are searching for the wrong thing - 'polar' is probably referring to ice blue colour, but differently named themes are available - e.g. the ones here, as well as loads available on gnome-look (example), the noobslab PPA, DeviantArt and elsewhere... – Wilf Sep 15 '15 at 21:17
  • What I particularily like on that theme are the way they designed the minimizing/closing window icons. – empedokles Sep 16 '15 at 10:33
  • Depending on your desktop (it can be done with Gnome 3's Tweak tool, not sure about Unity's) you can use that theme's window button metacity theme along with another's themes GTK theme - or just copy the pictures out of the metacity-1 folder over another's themes - this may require editing the relevant metacity xml file.... – Wilf Sep 16 '15 at 11:11
