On the colours of the rainbow.

Treat of the rainbow in the last book on Painting, but first write the book on colours produced by the mixture of other colours, so as to be able to prove by those painters’ colours how the colours of the rainbow are produced.

Taken from The Notebooks of Leonardo da Vinci edited by Jean Paul Richter, 1880.
