That seems unlikely. Look at fashion and decor magazines from the past and you see lots of lively colours that are coordinated. If you go house hunting and see a couple houses that haven’t been updated for decades they have a definite palette.
Could possibly be because most households nowadays have to be dual-income, and so there's not a dedicated homemaker with the motivation to do that.
Sad, like the "colors."
What is in fashion or decor magazine and what people actually have in home or wear are two different things.
Magazines are a reflection of a narrow slice of reality, usually the slice that could afford to buy the stuff advertised in magazines. Anyone can buy a magazine and aspire to the lifestyles depicted, but most can only aspire.
