I'm not sure how they could possibly represent everything they offer, because there are so many different colors and combinations possible. However If you go to the top of the web page to About Us and then Look Book 2014. After you are there then download the Look Book it gives you a better idea of the various colors and combinations they offer based on previous shoes they have sold.
After seeing your post, I downloaded the look book. Very helpful, not so much for leather colors but for model numbers and how the different models look on different lasts.
