Please remember that it is possible to confuse VA's colouring code with symbol names that are both classes and variables, since it has to run very quickly.
Still, there is something a little odd going on here.
uuid is a valid MS C++ keyword when used with __declspec, so, this is most probably the reason why it's rendered in blue. The same happens with variable named dllexport, for example.
