I'll occasionally ask a friend or in guild for someone to pick a color, then I make a mog around it. Between PvP queues with my buddy Prynne, I asked him to pick a color. He said brown instantly, and I knew why, he's a wiseguy. I accepted the challenge, and made the brown set after a few bgs. My other set was inspired by the Blue Overalls, and I knew I had to pair them with the Shovel of Mercy. It was a mostly "for fun" set, so I didn't fine tune it as much as I'd have liked due to laziness (I wanted more of a lamp looking off-hand). After I was done I dubbed it my Gravedigger set. Close enough! It was fun for a few bgs lol.
