White. I love how a red or white z looks with black or cf accents. Black is super sexy but everyone talks about the clean issue. Thus I'm preparing myself mentally. But if it gonna go black might as well go BLACK with 'super jet black' from dupont. I've read that mixing candy blue in with black gives it a deeper color as well.
