I suppose I really should have said good practice rather that correctness.

My LED class uses a boolean state attribute, if the state is True then 
the LED is filled with the on_colour. I had in mind creating on and off 
methods that set the state rather then directly setting the state 
attribute. From what I understand setting the state attribute directly 
is good practice.
