its hard to judge paint by the can but two pearl is an aditive tou add right before u paint either liquid or powder form so his color may be right, but keep in mind a lot of shops are crooks and will do watever it takes to make a sell. also a real paint shop mixes theyre color not purchase pre mixed ****. this is du to paint can go bad to so question is y does he have enough paint sittin in a can to paint a whole car and how old is the paint??? id jus go with ur gut but keep in mind u cant jus take it off if its wrong and u make him redo the job hell only scuff it up and reshoot the color and clear addin more paint on paint and weight and if u chip it it will be a deep cheep due to unnessary paint build up.... whew ok sorry long i know....
