What’s with Beige?

It seems like many Millennials I know live in homes of Beige. The rooms have walls, furniture, and carpeting, all subdued, bland; if not beige, it’s taupe or pale grey. That’s even the color of their bedroom. They seem to subscribe to the notion that the master bedroom should be “restful.” I think it should be a place for hot sex. If I say, “Paint Red!” they look at me mouths agape and shudder.
