I agree that most waste tanks are black in color, but most are not "black" tanks, only those that have a toilet connected are considered "black" tanks, whether sinks/showers are plumbed into them or not.
Your kitchen/bathroom sink or shower may drain into a black colored tank, but are still considered "grey" tanks.
I would also suspect that by any coincidence that the grey tank may have a grey handle or that the black may have a black handle was not in any way intentional by the folks at the factory, but purely coincidental & dependent on which pile/box of valves they grabbed out of at the moment.
