Depending on which expert you talk to, humans can perceive anywhere from 100,000 to 10,000,000 colors. However, judging from my quick and sloppy field research, Colorado cabin owners can see only three colors: Standard Brown, Official Brown and Identical-to-the-Other-Two-Browns Brown. There's the occasional cabin stained a different color, though. Those must belong to color blind people. Or out-of-staters.
