PC colour question

[CDNSushi]

1) If you were to have a coloured one is it still black tie formal? would it look out of place?

It's formal, yes... But would it look out of place? Let's just say that if there's a sea of black and you're the only one wearing a different colour, then of course you'll stand out. The real question becomes, do you WANT to stand out? Is it appropriate to the occasion if you do indeed stand out?

2) If you were to do it in a different colour what colour would you do?

Cobalt blue with black brocade shawl collar.
