What are the official illustration colors for network layers representing LAN, ISP and NSP.
I suppose they are based on the network layers but cannot seem to confirm this.

Specifically, to represent LAN, ISP, NSP.

There is no official network coloring scheme i know of.....


In general Red is considered DANGER, Stop, watch out....   (Internet side)
Green is considered OK, safe (Local LAN side)
Amber/Yellow is considered be warned....   (DMZ)....
well that is if you follow the international agreed upon trafficlight schema

I have seen more colors used to distinguish multiple VLAN's each with their own color, and Grey being used for Trunked connections.
(Purple & Pink for FibreChannel fibers).

Sure but I'm not looking for status colors but the colors which would represent lan, isp, nsp. That's the problem. I have to assume there are certain colors used for certain networks extending out from the lan.

I didn't mean status color, but colors of the cabling...

There is NO standard for that...,  
the ones i have show Red, Green..., and Yellow are commonly used.  
There is a firewall that represents Wifi with BLUE (for air)... it really is up to you...   (and availability of colors at the show you buy cables from ...)
You can have ANY color if you buy cabling by  1000m lengths.

Yes but I'm not asking about cables or cable colors. I'm asking about diagraming. When creating diagrams which include lan, isp and wan connections, what colors to use for each.

Again there is no standard. You can choose your own.
I just gave examples of customary chosen colours. Most network manager make the color in diagram (coarsly) match  cables. / or cable markings.
