Think of desert wrecks

When I sell an outdoor umbrella to a customer, they often ask if it will fade. And they phrase it like this: "This fabric won't fade, will it?" Ah! The set-up. Of course it will fade eventually. Is there anything that does not succumb to the sun? Images of bleached bones, desert wrecks, and graying wood flash through my mind. Hail the power of the sun!
