Post Accident Paint Blending???

Fullmetal

Heya, good afternoon forum folks. Im hoping I can get some insight here..

Recently someone hit my front bumper in a parking lot and drove away (really ****ing lame). So I took it into a body shop to have the front bumper replaced. They replaced the bumper and painted it the same color as the rest of the car (pearl white), but unfortunately they weren't able to get the white the exact same color as the rest of the car... So they want to "blend" the new paint up onto the rest of the body a little bit.. Honestly it seems kind of shady..

Is the Nissan Pearl White a special paint thats blended uniquely at the plant thats hard to replicate?

Anyways, thanks for any insight.
