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
...
