IMO A single, quite wide white stripe might look good on it?
I would agree your thinking that the black stripe(s) would not stand out enough and the red ones should be in the same Chili Red shade. Silver or some other shade of gray would probably make it look too a bit too much of everything so I would stay with the basic colors?
Since you already have the red highlights on it, I would continue on the path chosen and go for something bold and the white one should at least stand out on it
Or go for black stripe that would go from bonnet and across the roof? Perhaps aligning it a bit (1/3?) from the center line of the car?
BTW, really like what you've done with it so far. What's the color of your interior?
