You mean the nearly jet black fascia? Hm, I never thought of it as gray. Anyway, I am planning a limited production of jet black buttons to match the fascia. They won't let any light pass through, but holes could be drilled to light them. Or, they could be a base for experimentation; silver coating, chroming, gold plating?!? And I have a silly name for them too, but I'll release that when (and if) they ever are created.
