It was not only the day that abounded in colors. Van Gogh brought out the colors of the night as well. Previous Provençal painters had depicted the night sky as groupings of little white dots on a dark background. However, when we sit under the Provençal sky on a clear night far from the glow houses and street-lamps, we notice that the sky in fact contains a profusion of colors: between the stars, it seems a deep blue, violet or very dark green, whereas the stars themselves appear a pale yellow, orange or green, diffusing rings of light far beyond their own narrow circumference. As Van Gogh explained to his sister: “The night is even more richly colored than the day…If only you pay attention to it you will see that certain stars are citron yellow, other have a pink glow, or a green, blue and forget-me-out brilliance. And without expatiating on this theme it should be clear that putting little white dots on a blue-black surface is not enough.
