Lisette moto jacket accessory colours

I went to post this on the Lisette forum but I see it is no more??? Anyway, as part of the many things on the to do list this school holidays, I want to finally sew the moto jacket for my eldest. She has chosen hot pink stretch denim which totally fits her personality and even though it definitely doesn't fit within the colour scheme that seems to dictate moto jackets at the moment, it will be something that can be trans seasonal. What I really require assistance with is choosing a suitable accent colour for the zipper and any other accessories that are required. Because the metal zippers don't come in hot pink you see, so even though even this would be hard to match, we have a choice of white, grey or black. Any suggestions on what would be best? Or would it be better to just use the beautiful burgundy suede I was saving for myself instead?
