Exactly Guy!

We can display hundreds of colors on nodes and links... but, so what!  The old 7+/- 2 rule works well... and that is for the combo of node/link/hi-lite colors.  We can do more mathematically than we can understand visually.  

Another factor is the audience... are they network thinkers/perceivers?  We SOCNET members can probably see more in a network diagram than the common person... keep it simple.  We show various simple slices of the whole plus the one complex overall picture.
