Yes, in oldcpp the member variables usages were colored in orange both in
header in source files,
while for clangcpp the member variables usages inside cpp file are colored
in dark blue, and usages in h file are colored in orange.

See attached screenshots.

-----------------
Milian: For reference: A use of a member in a function outside the header does 
not find the member. Probably all thats missing is the import of the class 
context in the function body context.

And this got even weirder now:
1) Create an empty project
2) repace main.cpp with following code by pasting from clipboard:
class Bar
{
    void foo();
};

Bar createBar()
{
    return Bar{};
}

void Bar::foo()
{
    return Bar::foo();
}
3) the uses inside createBar and Bar::foo are navigable, but Bar in
function signatures is not
4) close the main.cpp file in kdevelop
5) close the kdevelop
6) clean kdevduchain (rm -Rf ~/.cache/kdevduchain/)
7) open the kdevelop and let it automatically parse the project
8) open main.cpp file
9) Bar in  "Bar createBar()" and "void Bar::foo()" is navigable, but the
functions body is not (and is not colorized)
10) press F5
11) function body is colorized and navigable again, but Bar in function
signatures is not anymore
