I actually purchased both color options of these for my baby's nursery.  I'm having a daughter and thought the yellow/blue ones would be perfect for her nursery early on, while the orange/pink ones would be great for when she's a bit older.  The colors are very vibrant, sheer to let in plenty of light, and I couldn't be happier. 

Pros: Colors are true to the image, great quality. 
Cons: None.
