Does he want the category colors to be different from the rest but the same as each other or having them all a different color from the rest?

I dont know. He only has to category and the ones he has are the ones he said he wanted to be a different color so I dont see why he doesn't just change the color of the category strip in the admin panel like I said.

To confused must leave before brain explo ..... [insert explotion sound here]

Explaining good would be a first step. :) :p
