Indeed, we solve the former problem using the latter solution.  If  
uses the wrong color, we require them to do the following:

	1.	Do NOT install the cable into the cable management.  Leave
		it hanging.

	2.	Use labels to label the intended color of the cable at each end
		and at 2' increments along the length of the cable if it is more than
		3.5 feet long.
