How to fix colours in the Software Centre?

Question

The Software Centre on Ubuntu 13.10, 14.04 and 15.04 is showing up a colour scheme that renders the text hardly readable:

Apparently, it is mixing colours from the desktop theme with its own theme and the end result is somewhat of a blur. Is there any way to fix it?

Answer 1

1. Open up a terminal and type the following command:

   gksudo gedit /usr/share/software-center/ui/gtk3/css/softwarecenter.css
   

2. The first two lines should look like this:

   @define-color light-aubergine #DED7DB;
   @define-color super-light-aubergine #F4F1F3;
   

   Copy and paste those two lines right below then comment out the originals, by enclosing them between /* and */. Change the two HTML color codes (#DED7DB and #F4F1F3) to your preferred dark colors so that dark text will show up.

3. Save and close Gedit. Launch Ubuntu Software Center to check out the results.

   As an example, the first lines of css file now look like this:

   @define-color light-aubergine #CD4634;
   @define-color super-light-aubergine #CD4635;
   

This colour scheme is Numix orange.
