Da Vinci Notes 03: Aerial Perspective and the Blue of the Sky

Why the far hills turn blue and then pale, why dry smoke is blue before black velvet and ashen before linen, and what I saw above me on Monboso.

Leonardo's aerial perspective: five times as far, five times bluer, the smoke and velvet test, the Codex Leicester blue sky, and what Tyndall and Rayleigh found.
