The black is a reversible panel that was almond (IIRC) on the other side. You could take the panel out completely to expose the textured white finish, which matched our GE fridge. When we got a black glass door GE range, we switched to the black panel.
Thing washed great, but we had to replace the lower wash arm s couple of times as it wore threw, mostly near the ends on the bottom. That forced much of the wash water down toward the bottom of the tub, making it splash out below the door and above the access panel. Water all over the floor. I guess there was something wrong with the plastic, or its reaction with my water or detergent. Anyway, when the motor went we ditched it. Only had it 8-10 years, I think.
