Desktop Notification Theme

Where does Mate store the theme files for desktop notifications? If I go to the control panel and select the desktop notification option, it shows that there was several different themes, but I can't seem to find where those files are stored.

I want to modify an existing theme to match the color scheme my desktop is using, because the current theme options look out of place at the moment. Any help toward achieving this goal is greatly appreciated.

I'm afraid, it is not so simple task.

You have to edit source code.

After doing a little research I am wondering if it would be possible to perform the following steps to modify an existing theme with the colors I would like to use:

Would this process produce a shared-object file that I could just copy over to my actual system in the directory you mentioned in your previous post?
