There are many other differences as well. Though colour isn't an accurate measure, and size isn't always accurate either, but saddle shape can be quite distinguishing between the two subspecies. BCI tend to have either a "circleback" pattern to them, or saddles that dont have peaks in the middle - )( whereas BCC tend to be more < > shaped. BCI have 22 - 30 saddles whereas BCC have 14 - 22. Hope this helped
