Trying to color vector and it will not let me add no color to the center of the letter.

Read up on Compound paths in Illustrator. Sometimes, even if you make the paths compound, the counter still doesn't knock out. This is due to direction each path is drawn: when such a path is drawn, like the letter "e" in my attached sample, the path starts at one point and then is drawn in one direction, either clockwise or counterclockwise and back to the starting point. For a counter to knock out, that path needs to be drawn in the opposite direction. Sometimes when a collection of letters is accidentally uncompounded, like yours, these directions can get mixed up.

Open up your Attributes panel and select one of the problematic inside paths with the Direct Select Tool and change the direction (indicated in green).

I'm curious how you got to this point anyway. Normally when a text object is made into outlines, it's already properly compounded; what did you do after that?
