The effect of colours in the camera obscura.

The edges of a colour(ed object) transmitted through a small hole are more conspicuous than the central portions.

The edges of the images, of whatever colour, which are transmitted through a small aperture into a dark chamber will always be stronger than the middle portions.

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