firebug

I'm confused with these colors. I noticed there are 4 colors showing in the left hand column of FireBug DOM tree:

Bold black
Black
Bold green
Green

In the right hand column:

Blue
Red
Bold green
Green
Multiple color elements representing object structures.

What do this colors represent? And why, e.g, I can access window.document.URL and I can't access window.document.body in Console even though they are both in the "not-bold black" category in the DOM tree?

Thanks a lot
