Mark, are you sure that's Smyrna 6210? It looks more like Auratium 5712, an earlier T5 color.
I know lighting and camera can both have big effects on perceived color.
Here's three in Smyrna: one off the web, one at Monterey last year (outside, bright sun) and mine,
dreadfully locked inside where only un-natural fluorescent light reaches the paint.

All three of these appear to have more blue in the color than your example.
I know mine is correct as we had both original Glasurit chips and some original finish inside measured to ensure a perfect match.
Mr. White, any chance of accurately posting some scans of your collection of factory color charts?
