Bedroom Makeover : Pillows

As I've mentioned before, I'm currently in the process of giving my bedroom a makeover. This makeover, however, has almost become a makeunder. I've painted by room a neutral color, purchased a creme colored upholstered headboard, & have decided to go with white bedding. So basically, my room is DESPERATE for some pops of color!

I am having the hardest time picking out the perfect pillows for my room. As I've been searching online, I've learned that I tend to gravitate towards subdued colors (mostly pink and yellow) but that I also like a little cool edge. Which pillows are your favorites? And why is picking out pillows such a challenging task for me? -O
