Since you are dispatching based on an instance variable, why don't you
wrap send and colorsend in another method that does the dispatching
and invoke this other method from your 50+ methods?

Btw, send is a bad name to choose because this is a standard method.

I also wonder why you have 50+ methods that are somehow similar.  It
seems there is room for improvement.  Maybe you can state the business
problem you are trying to solve.
