I would be interested in seeing the adult that grew up in that nursery. Like, do their meals have a side of fava beans and a nice chianti?
But then that second one is just bad. Like product makers don't understand the goal, thinking we actively like the color instead of de-emphasizing the walls, and we're stuck with it.
My entire dining room cost $600. All from FB. All solid wood. Buffet table, china cabinet, dining table, and six chairs. It must have cost $5,000+ when purchased new.
My peers would rather fill a home with monotone colors and disposable cardboard furniture.
So as a millennial all I can say is: Yay! I'll gladly take the stuff they're passing up.
In any case try not to worry too much about it, there are plenty of people with (arguably) bad taste in every generation.
No, it is (or was) definitely a trend. Google "millennial gray" -- it's so common it became a meme.
