In the early 1970s appliance manufacturers conspired to pollute American kitchens with a limited color palate of these three colors: Avocado Green, Harvest Gold, and Poppy Red.
And they got away with it!
Fondue pots were especially popular.
At about that time I was working in receiving for Dayton’s, the preeminent Upper Midwest department store. We would get pallet after pallet of cheesy kitchen goods: pots and pans, small appliances, even tableware—all of it in these three colors. Major appliances were furnished in this chromatic triad as well, with burnt orange and a brown also available.
Where have they all gone? Even antique stores seldom have any. You can get some custom appliance colors, but not at a reasonable cost. Earlier color trends such as pink and turquoise have experienced a dramatic resurgence, but “the big three” evidently wore out their welcome by the late 70s. Dusty Rose, Lavender and other pastels were trending in the 80s, while various creams/bisques/beiges were big in the 90s (i.e., my kitchen). Now everything is black, white or stainless, in kitchens painted gray.
