Where did you buy this stuff? eBay? It is always good advice to stay away from eBay if you're not sure what you're getting.
First of all, compare the part numbers (I know you probably did this before ordering, but it doesn't hurt to double-check). Behr is a good brand, and it is probably what you will get if you buy the parts from the dealership anyhow. If the part numbers match, I would be inclined to say that you got the right stuff even if it looks slightly different.
How different are things? Do you have any pictures to share?
If you decide to return that stuff, don't buy from the dealership -- there are places online like autohausaz.com, pelicanparts.com, bavauto.com taht are reputable.
Have you contacted the seller to verify there wasn't a shipping mistake?
