“In nature, light creates the color; in the picture, color creates light. Every color shade emanates a very characteristic light — no substitute is possible.”

“Light in nature creates movement in color. The movement is provided by the relationships of uneven measures, of colors contrasts among themselves and constitutes Reality [In this quote Delaunay is referring to his series 'Window'-paintings', which he had started in 1912].”

“Since light is best expressed through differences in color quality, color should not be handled as a tonal gradation, to produce the effect of light.”

“Light, with its handmaiden color, was everywhere.”

“It seemed to me that it was possible to translate light, forms, and character using nothing but color, without recourse to values.”

“Colors are ghosts, they only start to exist when light is perceived on the retina as a stimulus and is processed into color perception in our brain.”

“Light is something like raindrops — each little lump of light is called a photon — and if the light is all one color, all the "raindrops" are the same.”

“For simple light is perhaps still more beautiful than colors.”

“Melody and harmony are like lines and colors in pictures. A simple linear picture may be completely beautiful; the introduction of color may make it vague and insignificant. Yet color may, by combination with lines, create great pictures, so long as it does not smother and destroy their value.”

“Nature's purpose in relation to the visual arts is to provide stimulus — not imitation... From its ceaseless urge to create springs all Life — all movement and rhythm — time and light, color and mood — in short, all reality in Form and Thought.”
