I am reposting this from my thread on grey shoes as I am really curious.

This is going to sound stupid, but it is a learning opportunity for me: how is it that navy or burgundy works better with dark grey pants than black?

I get taupe bookends my hair, but with the dirt and slush tracked indoors, taupe is a really tough color for footwear in winter. And, frankly, I don't have the time to care for it.

Wouldn't any of the other colors just add the same third color as black? And if I went with burgundy, how could that match teal?
