The exercise is to figure how to make initialize_colors work as a class 
method -- so if the instance vars are misleading, then it's those I 
would change.

I am just experiementing to understand with working examples how various 
syntax and behavior are related in Ruby to acheive various levels of 
functionality at the class, instance, and module realms.

Another way to look at this is that I'm trying to understand how some 
things in Rails work by replicating them on a micro scale -- in this 
case a good example might be how the validates_ methods all work. 
They're called as class methods from within a subclass and I would 
expect they're implemented via modules. I've traced the source, but 
there's too much noise for me at this stage of my Ruby experience.
