Thank you for the constructive critisism on the colors. I myself have been toying with th idea of trying to blend the different themes so that they somehow appear to be the same but different. Making the differnt variations of the Brown skins with one common color is a good idea. And your right most members do perfer the Theme titled Brown. so that would be the one id use to achieve this.
