Buy the correct color from Herb's Parts. They have their own line of interior paints. Try the paint on the back side of your black panels and see how well it covers. I just sprayed some bucket seat hinge covers with Herb's Pearl White paint. The pearl turned the black covers silver. I ended up having to spray them white first...then spray the pearl over the white.
I think black would be your best base color. If you get a small scratch, the black won't show through as much as white would.
