From movies, television, and car shows, but the two-tone paint was an option.

Charcoal/Silver 729
Inca Silver/Black 36
Panama Yellow/White 190
Regal Turquoise/White 252
Signet Red/White 756
Silver Blue/Silver 757
Snowcrest White/Silver 499
Tuxedo Black/Silver 199
(The numbers are slightly off which is likely due to the changeover from charcoal to black mid-production).
And the whitewall tires were a defining characteristic but no one is pushing to bring them back, nor the Corvette hubcaps.

Yeah, but the coves are still there in the 1958 Corvette, even in the monotone cars. They doesn’t exist on the Miata, and are only evoked by the paint. They are an easy visual link to the tribute car. If you don’t like it, that’s okay.
