New Persian Rug

I found this great handmade persian rug on Ebay for only $50! It's about 2.5x4.5 so it's not huge but it's a great size for our small office. Right now I'm debating on the colors. The red is fun and adds a little something to the mostly neutral room but it's red. And ever since I painted a wall red in one of my first apartments, I've stayed away from the color. So is it really true what designers say--that every room needs a punch of red?
