Colour shirt/tie with flecked black suit

Hi,

Any advice on what colour shirt tie to wear with a black textured suit with white flecks? I'm attending a wedding, and while it's hardly a traditional colour choice, it is a nice suit

However, while I have worn it once with a white shirt/red tie combination, I'm wondering if a light blue shirt and darker tie might not be a better contrast?
I didn't find the right solution from the internet.
