I\'m confused with these colors. I noticed there are 4 colors showing in the left hand column of FireBug DOM tree:
After digging into it a little further I got the answer:
In the left column:
Black are properties and green are methods. Bold means the member was declared "by the user" meaning the members aren't from the default javascript/DOM framework.
In the right column:
Numbers are blue, strings are red. Objects appear as a "instance preview" in which the type name and the member names are green and the member values are gray
