In doing a search for Bianchi Celeste I found everything except a picture of the color.
Blue Green, right?

Anyway, I came across this:

"The oldest bike manufacturer in the world, Bianchi brings over 150 years of experience to their bike line. Known for their famous 'celeste' paint jobs, Bianchi has been producing bikes for world champions and Tour winners for generations."

Oldest in the world, and Italian.
How interesting.
Beretta, the arms manufacturer, and an Italian company, has produced firearms longer than any manufacturer in the world.

The Italians seem to know something about metal.
