Why does Visual Studio gray out parameter names?

Question

Does anyone know why VS likes to gray out parameter names in a function? Is it to discourage reads/writes to the parameter stack allocation? Or perhaps to make aware of the fact that you are using the parameter and not, say, a class member variable? Just curious.

Answer 1

I can confirm @HansPassant's comment of being able to change C++ parameter font color in Tools > Options > Environment > Fonts and Colors > Display Items. Here is the original:

After the change:

I chose teal because it didn't seem to clash with other readily present colors.

At any rate, it was not colored grey because of the parameter not being used.
