Why Is the SEMA Project named The Black Rhino?

You wouldn't believe the number of times I get this question.  It's not a problem because I love the question mark it brings.  In fact, that's the reason, I named the project, the Black Rhino.  Black Rhino's aren't black. They're gray. The double takes or the second guessing is part of the excitement of building these projects.

But if you're wanting an "official" answer, here's as close as it gets from WikiAnswers:

"A popular theory of the origins of the name "White Rhinoceros" is a mistranslation from Dutch to English. The English word "white" is said to have been derived by mistranslation of the Dutch word "wijd", which means "wide" in English. The word "wide" refers to the width of the rhinoceros' mouth. So early English-speaking settlers in South misinterpreted the "wijd" for "white" and the rhino with the wide mouth ended up being called the White Rhino and the other one, with the narrow pointed mouth, was called the Black Rhinoceros

There is no confirmed explanation for why Black Rhinos are called black, but the theory is that since black rhinos are prone to wallowing, when people saw them, coated in dark mud, they thought that they were black in colour. Their actually skin colour is dark grey."
