The Mediterranean has the color of mackerel, changeable I mean. You don't always know if it is green or violet, you can't even say it's blue, because the next moment the changing reflection has taken on a tint of rose or gray.
Vincent Van GoghAt 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.
