Blue Couch?

So last night I walked into my hotel room and thought I had accidentally entered the wrong room. I surveyed the room for a solid five minutes trying to figure out what was different. Then I realized they changed the cover on my couch. It was red and now its blue. This makes much more sense considering I have one accent blue wall and a blue chair to match. It didn't dawn on me until later that the red couch was actually out of place in the room itself. I'm also kind of amazed that a simple color change to the couch changed the room that much.
