Neo-Impressionist method is an attempt is made to achieve the richness of the sunlight spectrum with all its tones. An orange that blends with yellow and red, a violet that tends toward red and blue, a green between blue and yellow are, with white the sole elements. Through mixture (in the eye of the observer) of these pure colours, whose relationship can be varied at will, from the most brilliant to the greyish. Every brush stroke that is taken from the palette remains pure on the canvas.
