U316 is based on a starboard photograph of United Tenorio on 7 July 2012: the star and wavy line are grey and the “7” white. In a port-side photograph of United Milos on 31 March 2012, the seven-pointed star and line look white, possibly because of backlighting. A port-side photograph of United Jalua on 15 May 2013 confirms grey.
