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.
