professionally mixed automotive paint in pint containers that needs to be sprayed w/ a gun >>>>>>>>>> going to autozone and getting the spray can shit which in and of itself is its own variant of the base color
if you REALY want a great match, find out what brand of paint vandit will be using, then go to a shop that has a paint scanner (and uses that brand paint) and get your color scanned, then give the resulting code to vandit
some colors have up to a dozen variants, a result of the MFG changing paint brands, spraying techniques, prep techniques, paint additives or just plain screwing up a run of cars
