Meanwhile, my local body shop has a whizzy web-cam in a tube thingy that they hold over a paint/colour sample and it gives then a mix formula in about 15 seconds, for which they charge nothing. Mean they can match aged paint etc apparently, though of course the finish is better unless you cut down the old stuff. If you do, it's perfectish, even under sodium lights.
They are actually made from whale's ear-wax.
