The chance of finding wire in all the colors you need are probably slim to none. Here's another idea that has additional benefits. Get a copy of Bill Taylor's "modern" wiring diagrams.

This page is a tremendous Pantera resource! I'm surprised it hasn't been mentioned already in this thread.
Bills diagrams are modern in the sense that they are circuit and function based, just like they are for all modern cars. Then, as you replace a wire, mark down the new color on the diagram. Simple as that. BTW, there are multiple std. Pantera wiring diagrams which are available lower down on the page.
