Nüsse’s original table-flag photograph supplies this blue shade. The funnel appears on Rainbow to starboard in dull light on 5 October 2010 and Kamari to port on 14 February 2013. A later note identifies Calypso N’s funnel with N181 but says the drawing is darker than the actual colour.
The newer Nüsse website gives a different blue. Annika’s port photograph of 5 May 2007 may support the lighter funnel shade, consistent with Mitchell, though Rosanoski questions whether the photograph’s colour is natural.
