Messy yes, but in my actual use-case the Loader is part of framework code and the 
"blueRect" is a Component provided by the user of said framework, so I have no 
way of knowing which Behaviors the component has.

Posted this suggestion to address the problem:

It might be a bit on the messy side, but you could bind to the 'enable'
property of the Behavior. Before you set the color, disable the
behavior, then enable it again after.
