I don't follow the trends either. But I have seen way too many grey living rooms. Grey top to bottom
In twenty years grey will also be considered very dated,
There has always been colours that were very popular, way before the advent of the internet, and everyone used them. And many people still remember them being everywhere. Hence they are unpopular because they remind people of the eighties, or nineties etc. Everyone remembers peach walls, or terracotta or purple ones, pastel shades, chintz, burgundy, brown, magnolia being every where.
The colours currently coming into being popular, the navy’s, the greens, the coppers, the dusky pinks, have not been very popular for a very long time. In fact I can’t recall a time they were and I’m 52. So they don’t remind people of a rather dated living room. They are all new and shiny for most folks.
As I’ve said on previous threads, my house is predominantly different shades of green, with some notable funky But beautiful wallpaper in places but I did that before it became “trendy” . But greens and beautiful wallpapers weren’t dated either, it just was my taste and not really anything. The fact it’s now coming into fashion is irrelevant and not something I could have foreseen.
People should decorate their homes as they like, but things that become unfashionable is because purely most people can remember a time when they were everywhere, like today’s Grey, and thus they look dated.
