What color car seat covers work best for a gold car and light tan interior?

What color seat cover would work best with a "champagne" (goldish) car with all light tan interior. I feel like black would be too dark and would be out of place, and I feel blue and tan don't really go together. I don't care for reds, oranges, pinks, or yellows... I'm having a really hard time finding tan seat covers, though if it doesn't match the rest of the interior, I feel that would also look pretty dumb...

Suggestions for colors or stores to go to? I really don't want to pay more than $20 or so for a seat cover (so no fancy-schmancy custom covers or anything).

It's a 98 Mazda Protege if that matters. I know the styles of seats differ, and I'm not really sure what kind of seats are standard in Proteges (Does anyone know?? The car didn't come with the owner's manual, I bought it used).

Thanks for your input!
