I have traded thousands upon thousands of tokens to that guy for robes, using the cheapest trade in value (50 per). The robes are very colorful... however the top accessory layer on these particular robes (the shoulder piece be it a collar/backpack, the harness, or the shawl) vary rarely has any attractive coloring. I've had entire inventory pages of robes with the upper accessory layer being variations of white, gray, beige, maybe yellow green, and pale aqua. I don't know why. Now I have never traded for the Exceptional stuff so I have no idea if the coloring for those pulls from a better list.
Are you particularly looking for an earth tone robe? I might have one.
