I have seen bags of many colors advertised, all labeled BT, but not owning anything in BT, I cannot be a judge. There is a warm light brown which I like and also a warm dark brown which I love. I believe that is called mahagony, but not sure. I have looked at the color swatch pictures in the catalogs, but they are no big help. Often when I look at the rehab pics, the original color is a poor shadow of the final result. In this case I do not know if the result is due to the moisturizing of the leather, or the subtle influence of the "lotions" used.
