I cannot coordinate to save my life!

I'm really hoping you ladies can help me here. I am trying to find *matching* bedding sets for my 4 year old SON, and my 6 year old bonus DAUGHTER. It'd be so easy to just do pink and blue, but my son would want the pink one over the blue, so I'm looking for something that can work for both genders. Please help a mama out! I've looked everywhere and nothing has stood out.
