You can use a hack like
class Base(object):
def __init__(self):
module = __import__(self.__module__)
self.library_color = module.library_color
But I think it's better to add another level to the class hierarchy:
class BrickBase(object):
def __init__(self):
self.library_color = self.library_color
class LibraryBase(BrickBase):
library_color = "blue"
class BrickDoSomethingN(LibraryBase):
pass
(all untested)
