I just turned the wheel and pulled this out. The rest are still in the car. And I don't have new plugs, I'm debating getting new ones. The car has 58k miles.

They look good color wise. They should be changed around 30-37K miles so you did well and will notice it when you change them. They run 50-80 bucks(ebay or sparkplugs.com) and get the OEM ones by NGK, they are the best.

Actually they seem unusually light to me. Do a light of high-rpm/high speed driving? If not, double-check the heat range on the plugs; maybe they gave you "hot" plugs. Which may not be appropriate depending on your driving conditions.
Considerable ash deposits and the center electrode is well-rounded, suggesting these have been in service for a long time.

Those are the best plugs I've ever seen on a RX8.
No fouling fuel. No black at all.
If he was lean they would be much lighter and yes plugs do change white when they are too lean.

brown is good
black = bad.
Rodger: you've got 50,000 + miles, don't ya? Might be time to replace them
