Nice.

The basic idea of pointillism, was to generate colour, not on the canvas, but in the space between the canvas, and the eye.

In other words, instead of simply painting a section of a painting orange, they would instead use many different dots, in shades of red, yellow and white (the three basic colours required to make orange). When the eyes view these dots all combined from a small distance, it perceives orange, even though it is actually made up of dots of all three colours.
