Plum Crazy color ?

Well as a painter this really isn't all that surprising....IF you paint or have painted, the factory remains the type paint used, and the amount of metal flake (IF ANY was added in), and the type of primer, and then base coat, and how MANY coats were used on any one piece being painted....Plus each manufacturer of the paint and pigments used in it each one work differently, so X amount of this or that can lead to "close" but not exact UNLESS mixed all at the same time, by the same person! And even then the painter himself, would have to keep a steady accurate count of how he applied, and how many coats he applied AND how thick or thin EACH COAT was when sprayed....

And then of course in lighting how it hits, and what "shadows" you might have from body recesses and body lines....

Really, there ARE a lot of factors to "match" paint.....
