Color - Had a similar question a couple months ago on my 37. While there was no final ruleing, consensus was that black was stock. Cleaning and blasting them pretty much confirmed that they started out black. I still powder coated them Brewster Green cause that's the body color
Rivets - just mounted 2 of the 5 using tubless and they've held 50# pressure for a week now. (they're 8ply) I pinged each rivet listening for anything sounding loose
