Much like the colored and printed couches and chairs that normally adorn your grandma’s house, using too many colors and patterns in a single room is just as horrible. Having curtains, walls, furniture, bed sheets, flooring and tons of other items in the room that are all contrasting in one way or another, it’s going to make the room look both antiquated and distracting, no matter what you’re looking at. Unless of course you’re trying to make people feel that way.
