Way to Change text colour of icon on Desktop|Ubuntu 12.04 desk

If you are jaded with text color of your icons on desktop, then you just need to make few changes. Here are steps:

Go to path:

 /usr/share/themes/Ambiance/gtk-3.0/apps/

This path is for Ambiance  (theme in my case), if you are using Radiance or something like that, don’t worry. Make a little change in your path. Replace Ambiance with a theme you are using.

Now, in apps you would find a file “nautilus.css”.

Look for a line:

color: @bg_color;

Replace the @bg_color with hex code of color you want. It would be better if you uncomment the above line and copy it to replace hex code of color.

/*color: @bg_color;*/

color: #FF0000;

Then you will get your own color .Enjoy !!
