Well that certainly does bode well for this idea. Utilizing structural colors is the most permanent kind of color we can make. In fact, fossils of beetles can still be quite colorful even after millions of years in the ground. UltraStable is good.. but this kind of color is epoch.

(pun intended... )

That frontispiece you mention can be seen here... http://archive.org/details/cu31924031248119

My university library has an original copy of this book and it's one that really got me into this early color stuff. A very interesting read for sure. Cutting edge color photography at the turn of the century, before they had it all figured out.

Thanks for your comment!
