Our first stove and fridge were the copper color. TI think it was called some two word name, which I can't recall. Then we also had the yellow....and almond. Now in the condo, everything is white...what goes round comes round, although Mrs S has cast a glance or 2 at the stainless finishes that don't show fingerprints.
We had some friends (whom we have lost track of over the yeras) who had a red set of appliance. This was in the '70's.
Hey, as long as they cook and cool correctly, they can be any color....well, almost any color.
