Old Gold
Demolition, Juryo, Knox, Mysterio, Superfly, Warrior
Alpha Imperial, Raider, Kevlar, Olive
I think that's it...
If you want an "easier" (read: easier when you have done all the settings) access to see the colors, you could use the in game feature ToriShop...
But now that it's not working properly...

Just extract 'em all to the custom folder in your Toribash 3.8 folder.
When you've done that, type...
/lp 0 [color]t
You type the name of the color and add t to the end.
So, if you want to see the color Demolition, you should type...
/lp 0 demolitiont
If there's a space in the color name, like Alpha Imperial, you just add the names together, like...
/lp 0 alphaimperialt
Also, if you want to make Uke look like the color of your choice, then just type
/lp 1 [color]t
instead of
/lp 0 [color]t
