What do the black and blue color markings in the PolySpace results represent?

I was able to run a PolySpace analysis of my C code successfully. Upon looking at the results, I see some black and some blue color markings in my code. The manual does not explain what these markings mean.

A black marking represents source code where there is no check on it. A blue marking represents the name of function or a link to a global variable.
