Terminal colors in Leopard

Hi I've found a post from yesterday that was helpful in setting colors to hidden files in terminal by editing the ~./bash_profile. I'm not sure exactly what all the commands were and I'm wondering if there is any way to extend these colors (perhaps set a new color) to other files like python *.py etc

Thanks

Ok, just had a bit of a look into it and I hadn't changed the mode of my python files, once doing that they have come up Red. However, I have a few pdf and doc files in the folder and they also come up as the same color. Is there anyway to maybe leave *.pdf .txt .doc files uncolored? .csv files seem to remain uncolored.

Sorry about all the posts on terminal colors...
