Correct paint for 2007 shelby gt

I just had a new front bumper and right fender painted on my 07 SGT.
The the car calls for HP high performance white.

The white that was put on he car doesn't match. Can anyone help with this issue? I overheard that the shop had problems matching the color. The white looks like basic white that was "messed" with to try and match the hood and door.

I picked up the car today and told the guy that I thought that the paint wasn't correct - he assured me it was correct. Under the florescent lights of my garage, the paint is WAAAYYYYY off.

I'm taking the car back in the morning, called the insurance company and told them not to pay.

Thanks for your help.....
