When I was doing the last layer of cement I mixed in some terra cotta coloring into the cement.  It is made by qwikcrete, and they have several different colors.  I went with the brick color.  It is liquid, and came in a bottle, picked it up at home depot next to the regular qwikcrete.  You have to be careful not to add too much water to the cement when adding it, because is acts like water and make the cement all soupy, and a little bit of the color goes a long way.  Then I mixed a little regular colored cement and kind of made some highlights in grey to give it a 2 tone look.  Try it out if you build another background, I think the bottle was 5 bucks.
