The download contains:
- GTK & Metacity theme
- Google Chrome / Chromium Theme
This themes is a mix of engines,I have picked what I liked more from them. Also, I have used some elements from other authors.
Note: You can edit colors (selection, window's background, etc) in appearance window in Ubuntu.
If drag & drop over appearance settings doesn't work, try to extract the file and copy his content to /home/~user/.themes
