Hey Nashes,
The bumpeh was noticed

Let's see if I can get this sorted. A few remarks/questions first to clarify things for me:
On default colorsThe default color values refer to the ID value of the ColorDesc nodes lower in the file under ClothColors. You're trying to fill those IDs in where you put 'x', right?
On custom races in generalBe sure to use a "hero" root template with a hero visual set. (Or make your own of course.)
If using a normal npc set you might run into difficulty with properly equipping and using equipment loot.
On changing colorsYou can't seem to change the initial color then, according to what I understand. But are you also unable to change the color in character creation? (Also when using a "hero" root template, if this wasn't the case yet).
You can also find some accompanying info on this in our (work in progress)
character guide.
Sincerely,
Kevin
