Crux of the matter with that color, you have to blend.
Sun damages the paint, so even if you get the exact color that the factory uses, it has to be adjusted due to the sun/acid rain damage, this is difficualt, and the differance between a good and bad panel shop.
By blending, you actually lighty spray the adjacent panels as well, to take the glaringly obvious affect away. On darker/metallic cars, color matching is very difficualt.
Something can therefore be said for white cars, it makes life a lot easier, although there are something like 87 differant combinations of white.
Market average is about 2 to 3k for a bumper, non metallic, and 3 to 4k for a hard color, something like saphire black is downright painful....
