"The starry sky at last, actually painted at night, under a gas-lamp. The sky is green-blue, the water is royal blue, the fields are mauve. The town is blue and violet. The gaslight is yellow, and its reflections are red gold and go right down to green bronze. Against the green-blue field of the sky the Great Bear has a green and pink sparkle whose discreet paleness contrasts with the harsh gold of the gaslight. Two small coloured figures of lovers in the foreground."
Van Gogh describing Starry night over the Rhône in a letter to his brother Theo
