I have a problem with dark theme. I'm using Ubuntu Studio and Nox theme. Unfortunately I cannot see youtube like/dislike ratio because its font with this theme is almost white. This problem rarely concerns option bars on other sites. Also in software center after selecting a program, font is unreadable because of white selection background and white font. Can I change colour of these fonts? Or maybe you could recommend me some other dark theme that would be good for my eyes – not too dark and with low contrast – and without any issues making some program unreadable because of its unsuitable colours?
If you are using Xubuntu, open Theme Configuration. If you have only installed Xfce from another desktop environment, then you can paste
sudo apt-get install gtk-theme-config in terminal to install. Launch the application and change the top category Custom highlight colors to your preferred colors. Log out and log in again. This should fix the issue on Ubuntu Software Center.
To fix the YouTube Like/Dislike text, go to the
gtkrc file you downloaded with this theme. I installed for my testing by going here. Then I named the file .gtkrc-2.0 and placed it in my home directory for it to be activated on my system. However, you may have the file in another location. Open this file. Go to the line that starts with
gtk_color_scheme (line 60 in my file). Change this
fg_color: #EEEEEC to this
fg_color: #686A6A or whichever darker color you prefer. This color matches the hexadecimal number for the little thumbs up/down icons on YouTube. You may need to log out and in again for changes to take effect. However, this was not necessary for me. I only needed to restart Firefox.
If things are still not optimal after these changes, I fully understand where you're coming from on this. I always want my themes to be 100% perfect to my liking. It is great that with enough knowledge and persistence you can make things just as you like. You may want to try out a few other of these themes if you haven't done so already. Numix Dark Theme is probably pretty nice. I've also seen Spatry talk about some cool themes. If you dig into the config files after installing a full theme, then with enough persistence you can usually figure out how to change little aspects. My previous post here may be of interest.
