Full title of the famous marine painting: Snow Storm - Steam-Boat off a Harbour's Mouth Making Signals in Shallow Water, and going by the Lead. The Author was in this Storm on the Night the "Ariel" left Harwich. The painter, Joseph Mallord William Turner, pretended having been tied to the mast of a steamboat for 4 hours during a storm to experience the feeling of it. Finished in 1842, the painting inspired the Impressionists 30 years later. Currently in the collection of the Tate Britain in London. Light is therefore colour. (J. M. W. Turner)
