Correct. There's no Color.red and MoreColor.red. Subclassing is allowed
only of enums that define no members. So this is forbidden:
>>> class MoreColor(Color):
... pink = 17
...
TypeError: Cannot subclass enumerations
But this is allowed:
>>> class Foo(Enum):
... def some_behavior(self):
... pass
...
>>> class Bar(Foo):
... happy = 1
... sad = 2
...
