Thanks man! i'm looking forward for the solution!
I'm assuming you have icalBuddy installed and working properly other than the color part.
Open Terminal and type icalBuddy editConfig
This should open the .icalBuddyConfig.plist file in TextEdit
Use this guide to help with what code can be used. I'm guessing that you can figure out what to do by looking through that guide and knowing where to use the code.
If all you want changed is the time to be green, replace the code in the file with this and save, then refresh geektool to see the changes:
