I would go wine with navy stripes from Thurston, but buy a brace that will compliment your wardrobe nicely.
or if you want to spend the money, I really like this Trafalgar brace, but it's a little less versatile—more for the country club I think.

Dark colors like navy go well with light shirts because it creates a nice contrast—You don't want your outfit to be monochrome. As for the ends on the Trafalgar brace, they're not necessarily better or worse, just a little more formal/dressy, as someone else mentioned.
First braces ever? Don't jump into Thurstons just yet. I own a pair, and they're very nice, but they're not that much better than these, on sale now. Get a pair in navy and in burgundy.
These are fun, too, and also on sale.
