What color paint for these hubcaps?

I just scored a set of hubcaps in very nice condition. They are going on this truck. Kinda a crappy pic, but its the white D150 on the left. A nice touch, an unknown soul brother parked right by me at the grocery store.

Here are the hubcaps.

I'm going to give these a little paint love. Does anyone know what color these should be? Obviously the fratzog and perimeter are black, but I think the circle around the fratzog should be red?

Inquiring minds want to know...
The fratzog is black as are the outside area. The circle on the ‘68 and earlier hub caps (that’s what you have there) were not painted red when they were new.
