Well seems there's very little interest in the subject. So I guess I'll just tamper with the files alone. If anyone is interested, I've uploaded a zip file with the images just changed to blue from green. Nothing special yet, but I do plan to change some of the icons to give it a better look and feel. Included are some screenshots.

To install, just copy the new images over. I did it through WinSCP. Make sure you make backups before changing anything.
