A good match if you're just considering color is the Dress McMillan sett in muted colors produced by House of Edgar in their 13oz. "Old and Rare" line. The yellow is a beautiful gold and the red is a really deep, rich, dark garnet color. You can see it here:

Note that this image is not a scanned swatch, but a computer-generated picture. The actual fabric is much better looking. See if you can find a swatch book and see it firsthand.

Cordially,
