Jim: you're certainly right. The problem is, Sargent's website lists "9 BMW reds" in their color option drop-down... colors like Amarena Red, Flame Red, Marrakech Red, Piedmont Red, Racing Red, and four others.
Was hoping I'd be able to identify the color of the pinstripes based on BMW's color description.
Think I'll reach out to my dealer and see if they can be of help.
Thanks for the thought.
