Interior scenes were filmed at Sunset-Gower Studios (former Columbia Pictures) the first two years, then at Rem-Mar Studios for the remaining years.
The kitchen cabinets look more lime green than avocado on my screen. It's hard to say if that and the turquoise are original, but those were popular colors in the mid 50's. When we moved into the house in '57, the former owners had the living room painted chartreuse and charcoal gray. The bathroom was Ming Green fixtures, maroon and black tile, and the upper walls painted cerise. My parents had the painter busy for several days, as they had far different tastes in color and style than the Spence's.
