It will be ok if the painter is on the ball and adds the correct pigments/metallics. Red is an easy color to match and the only portion that you should concentrate on is the side of the bumper, by the rear sidemarker, as that will be where the bumper will lay flush with the rear qtr panel.

Im trying to say that the rear portion of the bumper is at such an angle to the licenceplate area that the sunlight will make it hard to distinguish a proper match, again however, the side of the bumper aand qtr will have light hitting them at the same angle.

You might want to bring friends to look it over too. Check to see if the metallic content matches too
