I have always spray painted my multidot targets brown, and then like mentioned above, pic a spot within that target, it really helps come hunting. When I started hunting many years ago, the first season or so I shot one of those old time multi-colored round targets, with a yellow 10 ring, come that first hunting season, the few shots I did get a chance on with whitetail I didn't even come close, lucky for me I didn't wound an animal, after that in talking to other archerys they told me to just shoot at something brown, and it made me a much better shot while hunting game animals.
