Opinions- seat backs on buckets

[1970blazin]

I have one orig seatback from my blazer (black of course) and the other is broke. I made some from Aluminum and was thinking of getting them powdercoated. Which would look better?
If I powdercoat the Alum. ones what color should I do:
1. Interior Blue (chevy med blue I think) which matches the houndstooth color in the black seats.
2. Black
3. Or match the color of my blazer (Orig. Dark Blue)
Here are some pics to help the decision. Thanks for your input!!
