terminal colours

[brian]

How do I edit the colour scheme for gterm? After updating to F11, 
terminal is *almost* displayed the same, but certain things--like 
directories--are a different colour and are now unreadable.

I've looked in the prefs but can't figure out how it's supposed to work. 
There's a colour pallete but no way to specify what colour should be 
assigned to what. Surely there's a text file somewhere. I've poked 
around in my home dir but don't see anything for gterm.
