Ghostofmacbeth, As a black/african american/negro person, I appreciate the fact that you even asked the question. I applaude your attempt to be non-offending. Now personally, I am not offended by any of the terms you suggested, but I think I would go for something like "Black" or "Dark" as descriptors for your textures. Disclaimer: I am not speaking for every black person who may frequent this forum,...just myself.
