I'd prefer them with a navy suit, to a charcoal suit. Just saying. I think the tie would work slightly better with a navy suit, and the pocket square would, as well. And the suit color would serve to tie the necktie and the square together.
I assume you'll be wearing a white shirt.
Yes, white shirt--there are so many other colors, I think anything but white would be disorienting.
I see what you mean with the navy suit, too...a shame I haven't got one. That is something that needs to be fixed (next up on my to-buy list!) Though perhaps a pale blue would serve to tie the colors together as a navy suit would...
edit: or I could just go for a navy blazer / khakis, with the above combo. though a blazer / sportcoat & khakis is what I wear nearly every Sunday
