"At present I absolutely want to paint a starry sky.
It often seems to me that night is still more richly coloured than the day; having hues of the most intense violets, blues and greens.
If only you pay attention to it you will see that certain stars are lemon-yellow, others pink or a green, blue and forget-me-not brilliance.
And without my expatiating on this theme it is obvious that putting little white dots on the blue-black is not enough to paint a starry sky" - Vincent van Gogh, Letter to Wilhelmina van Gogh, the sister, written 9 and 16 September 1888 in Arles.
