I recently found a catalog that seemed to answer my question about the
fade-resistant colored board.  It is the Bainbridge Printed Catalog
published by Nielsen & Bainbridge.  In it is advertised a board called
Alphamat.  It reads: "Alphamat board has become an industry standard for
conservation framing, by meeting all of the Library of Congress
standards for paper preservation."  It is non-yellowing, fade and bleed
resistant and 100% non-acidic. For information about the nearest
distributor near you, call 800-631- 5414 (east coast) or 800-321-2934
(west coast).

We bought it and were pleased with it.  Of course it's too early to test
its fade resistance.

Sincerely,
Yolanda Warren
