Redefine/alias a resource in WPF?

Question

Is there a way to redefine/alias an existing SolidColorBrush (or any other resource, actually)?

Case in point: I have a brush in an external ResourceDic

Answer 1

    
        Red
    
    
        
            
        

        
    

I don't want to be dependent on the external reference, since the actual brush is prone to change in the future.

You'll still be dependent on the external resource, just not in as many places.
