What is the correct color for 67-68 lower door vents

Does anyone know what is the correct color the little lower door vents are to be on a 67-68 Barracuda?
I am re doing a red car with red doors, the old fresh air vents were painted red.

I got my new red door panels from Legendary and want to fix these vents before I install the new panels.

All the vent sets I have are black. I do have a not so good set of a Champaine or a rose or a very bad faded red?
So I know they made colors other than black.

I have found 1 pic out on the net of a blue door that had a blue vent? Original? who knows?

I can dye a black pair red and go back the way I had it, but want to make it as right as I can.
If they were black in a red door that is the way they will be, but I cant find any info for the color of the vent.

Something I have learned from this site is 69's do not have these vents! only 67 and 68.
I went and checked my 69's and no vents.

Thanks in advance for any help
