Two men in black jackets sit on a white bench at night on a cobbled courtyard.
Two men in white jackets stand at night on black pavement.
Black and white are different colors, so the jackets cannot be black and white at the same time. One cannot sit and stand simultaneously. Cobbled implies a different kind of road than pavement. Pavement is smooth and one material and cobbled is bumpy and comprised of lots of different stones.
