As you can see, by and large, people assign colors to functions. What 
color to what function varies like the wind. Unlike a previous employer 
whose colo-manager person insisted on using colors to represent cable 
lengths (Doh!), color -> function mapping seems pretty universal.

About 7% of the male population in the US has red-green colorblindness, 
so keep that in mind. Simpler schemes trump more complex ones (as do 
most things in networking) and makes cable-purchasing/stocking less of 
an issue.
