I was thinking more the "cherry snowcone planet"... Red rock would really have more red-brown than anything. I have some basing stuff I intend on using for my Necrons and my IG Mars armoured company (if I ever get around to doing that project after the umpteen others set before it). It is iron ore ballast from scenic sand train stuff. It looks great and ya just glue it onto a dark brown base. Never to be mistaken for ground beef or some Willy Wonka planet. Anyways... I like this servitor, just hate the base... hope I help and not upset.
