Stripe Color On My '68 Camaro

[minendrews68]

I'm getting really close to painting my Camaro. I've got the body work done and I'm finishing up a few things before I send it to be painted and buffed. The color I'm painting it is a dark charcoal metallic with four colors of pearl. (the pearl colors don't stand out until the sun hits it) Really nice color I think. My question is this, I'm wanting to do the SS stripes in a color that's almost unseen until you look for it. I don't want a contrasting color, almost like a ghost color. I was thinking either a lighter color than the dark charcoal, a darker, dark charcoal, or maybe even a black pearl. I need you guy's opinion on what you think would look good even if it's not one of these colors.
