Both funnels follow starboard photographs of DHT Ann in June 2013, dated 14 June for D583 and 8 June for D584. Rosanoski attributes the apparent colour difference to photographic manipulation and considers the white version correct. He suggests that D583 enhanced staining as though it were the base colour, while D584 was also cleaned up to emphasise white; the unusually deep-blue skies reinforce his concern.
