How would a burgundy and turquoise wedding look?

Have you compared fabric swatches? Here's a site that might help--

I am not David, but I don't like the color combo personally

Burgundy is best paired with other jewel tones or neutrals such as cream, beige, black, white, sapphire blue, burnt orange, golden yellow or chocolate brown.
Turquoise is a much lighter tone that is probably paired best with the neutrals I listed above or purple, soft yellow or gray.
