Value category of member enumerator

According to cppreference.com a.m is prvalue the member of object expression, where m is a member enumerator or a non-static member function[2];

Does it mean for object expression ie a.m where m is a member of a of enumeration type, the value category of expression itself would be prvalue?

As per my following testing, it does not seem to be the case. What did I miss?

enum class Color : char {
    Red = 'r'
};

struct Test {
    Color c;
};

void func(Color&&) {
    std::cout << "rvalue ref\n";
}

void func(Color&) {
    std::cout << "lvalue ref\n";
}

int main()
{
    Test t;
    func(t.c);
    return 0;
}

Output: lvalue ref
