I'm assuming that when you run this, you get the output "This is Blue"
followed by an AttributeError from Colors.Red complaining that the var
attribute is not set. If you want this to work, then maybe you should
set the attribute.

But as Laura noted, you probably don't want to be calling more than
one thing in your if __name__ == "__main__" block. Just call the entry
point of your program.
