I agree, it's a nice one.  I might note, however, that this solution is closely 
connected to the "\break" that precedes the bar line I'm trying to color.  
Remove the break and the coloration disappears.  Is it possible to color just 
the initial repeat bar line that occurs in the middle of a line?
