Manuel made up a couple more for eventual use in my '89 project...
Ebony / Ebony and Ebony / Holly:
One will go into my GP White on black, with Pascha seat cushion inserts (Pole Positions) '89. I like the white / black theme carrying through to the G50-ish shift knob, but stripes may not work adjacent to Pasha seat cushions.
The black / black knob is the fallback and does offer a bit of a retro look.
These are the important decisions that keep me up at night.
