I wrote a shell script that can change clock, notification and progress bar colors and also the carrier message on the locksreen and pulldown bar. The script is meant to be used on FRG22B and I'm quite not sure how it will respond to other ROM's/versions so use it at your own risk. If there is a good response to this I can make it into an app version.
