Pillow Perfect

I'm in search of the right pillows and it is such a daunting task! I thought it would be simple since we have a mocha colored couch and our living room is pretty neutral and in dire need of some color! But there are SO many pillows out there, and I can't seem to find the right ones that fit together without buying a bunch of the same pillows! These images really made me realize that I still need to think further out-of-the-box and try something different!
