Elba’s photograph of 15 February 2008 shows a funnel that looks black at a distance but appears dark blue on closer inspection. The flag seems lighter, matching the clearly lighter middle bar of E.
Ennerdale shows dark blue in April 2008 but the E395 version in January 2011, duller under overcast skies. Rosanoski suggests a change of shade; St Martin’s April 2009 photograph shows the lighter blue more clearly.
