In architecture, for the last 10 years, there has been a move to adding BLACK (not just dark, but #000) to buildings. Be that through carbonised wood, paint or metal cladding.
However, black, outside of a few applications, is a stupid colour for modern buildings. It gets hot, it collects dust, and degrades pretty quickly (unless its carbonised wood)
Then in LA about 5 years ago, people started dicking about with grey. Having got bored with the Italianate white/blue combo (or perhaps Jardin Majorelle blue) There is also a natural reaction to do something new, which means rejecting what cam immediately before.
this has gradually translated into grey shit for houses. Here in the UK, people are getting grey window frames, and sometimes painting the house grey. it should really be banned as it makes the house indistinguishable from the sky, which is a traffic hazard.
Personally when I got my house painted, I wanted a huge fucking rainbow down the side. But the wife overruled me. She wanted grey, I said no, so we agreed on titanium white, which has a pleasing algal green to it now in places.
