@vfrmedia @jk Some of that is just changing fashion. Here in the US, for instance, the '70s were the age of earth tones -- browns and greens. Then when that became unfashionable in the '80s people went for screaming neon, as a way of emphasizing that the old trends were over. Then by the early oughts that mellowed into featureless "minimalist" chic. And now the earth tones are coming back.I suspect part of the story comes from the production side -- different materials and processes lend themselves to different colors. But part of it was also just tastes evolving.https://www.vogue.com/article/why-1970s-interior-design-is-trending-again
