How do I read in an enum value from a file?

Hi Experts,

In my VS native c++ console program, I define an enum e.g. Color {RED, GREEN, BLUE}.  This is logged to an ofstream such as:

ofstream my_ofs("blah");
Color my_color = RED;
my_ofs << my_color;

No problem.  Later I need to read in this value. I'd like to do something like this:

Color your_color;
ifstream my_ifs("blah");
my_ifs >> your_color;

This does not work because the compiler doesn't know how to read in a Color type.  But it's just an int in actuality, so it seems that something like this _should_ work. Any suggestions on the correct way to do this?

I don't care too much if the file actually stores the text "RED" or the integer code for it. However, the former would be preferred (though, that way probably entails much more code).

Thanks!
