In this case, the attributes are not ints.. so If you defined that class functions that took it's attributes would need to accept an int, and if I passed max-int or something it'd be up to your function to go figure out whether my argument was a valid value for Color. The enum class gives you that stuff. The argument you'd expect would be instanceof(arg, Color) == True (I think that's how they did it) and if it was, you'd be assured that the value was a valid value for Color. So you could do it yourself, sure.. but to get all the little benefits, you'd have to do more coding than naming a bunch of ints in a new class.. It's subtle though. Not a wild game-changer or anything :)
