Sources for Multicolored Jacketed Wire?

[steveb@newkla.kla.com]

... well I finally figured out how to replace the ignition switch module
on the '83 ur-q.  If anyone would like the details let me know and I'll
post a more detailed procedure.  Anyway, I found that some of the wires
to the switch have been getting a little warm and I thought I should 
install a load reduction relay (in addition to the starter and headlight
relays I'm planning to put in).

I have seen single colored insulated wire lots of places, but I haven't 
seen wire with multicolor insulation.  If I'm going to be doing a lot of 
wiring I'd like to have some kind of color code that identifies them.  
Does anyone out there know of a source?  I am going to be needing some
fairly heavy gauge wire in some instances (I'm thinking ~10ga).  Since 
I'm not making a profession of this I'd prefer to find a place where I 
can purchase shorter lengths < 50 feet.  TIA for any info you can provide!
