If you are like me and love vibrant colours and struggle to understand the postmodern(?) obsession with drab palettes, I recommend the book Chromophobia by David Batchelor [1]. It contextualizes this phenomenon within broader western art history and is just generally super interesting to someone who has an interest in art and design but isn't embedded in that world. The main takeaway, iirc, is that this isn't a particularly new thing.
I've bought a few colorful items recently, 80's print clothing and a rainbow rhinocerous from Amazon (this for reference, because it's awesome: https://www.amazon.com/dp/B09DT5NMB5?psc=1&ref=ppx_yo2ov_dt_...) and it is strange how transgressive it feels.
