struct Color {
    enum Color_type : unsigned char {
        red=FL_RED,
        blue=FL_BLUE,
        green=FL_GREEN,
        yellow=FL_YELLOW,
        white=FL_WHITE,
        black=FL_BLACK,
        magenta=FL_MAGENTA,
        cyan=FL_CYAN,
        dark_red=FL_DARK_RED,
        dark_green=FL_DARK_GREEN,
        dark_yellow=FL_DARK_YELLOW,
        dark_blue=FL_DARK_BLUE,
        dark_magenta=FL_DARK_MAGENTA,
        dark_cyan=FL_DARK_CYAN
    };

    enum Transparency : unsigned char { invisible = 0, visible=255 };

    Color(Color_type cc) :v(visible), c(Fl_Color(cc)) { }
    Color(Color_type cc, Transparency vv) :v(vv), c(Fl_Color(cc)) { }
    Color(int cc) :v(visible), c(Fl_Color(cc)) { }
    Color(Transparency vv) :v(vv), c(Fl_Color()) { }    // default color

    int as_int() const { return c; }

    char visibility() const { return v; } 
    void set_visibility(Transparency vv) { v=vv; }
private:
    unsigned char v;    // invisible and visible for now
    Fl_Color c;
};

I want to make a global pointer to the values of "FL_RED" and "FL_BLUE" or "Color::red" etc. What would the type be and how would I actually point to it?
