I think same brand for programming languages is SUN Java and IBM Java for Java, 
GCC and MSVC++ for C/C++ etc..

And it certainly makes sense to use the same conventions no matter what vendor 
provides the compiler.

Different languages must be more like different type of bottles: medical 
supply, beverages, poisons.

And they do not use same color convention.
