The colors are exactly as shown online, and overall it's a very pretty set.  
The sizing runs small and if you have a pillow top mattress I'd suggest measuring before ordering.  The queen didn't come close to fitting over my queen pillow top mattress, and I wish I had ordered the king.  I changed it to a guest bedroom with a much smaller pillow top and still it's a bit too small, but not enough to hassle returning.
