Anyone know how to assign unique line colors in a plot call when there are a dozen or more data vectors?

Here I simply use 3 colors, r,g,b but want to automatically create a dozen colors, beyone m,c,y,k.

Creating a map of maximally distinct colors is not a trivial task (as many people think), but luckily you can find some tools on FEX that do this, such as my maxdistcolor tool:

Note that the quality of the output depends mostly on the quality of the colorspace that you use: I recommend using CAM02-UCS or CAM02-LCD.
