The vast majority of refrigerators I'm coming across are coppertone. I like coppertone! I'd seriously consider switching over from white, but the house still had its original white Kohler sinks (which have since been joined by an age appropriate white Kohler Wellworth toilet) and a discolored white shower stall. I also have a brand new pair of Speed Queens in white just off the kitchen.
It was a rental property up until we bought it. Maybe it had white from the start to keep it easy to maintain on the cheap, rather than trendy colors? I haven't found any other 70s houses in this area with anything original in white.
