Photographs of Red Gardenia and Red Lotus show the letters slanted “PBdS”. A Newcastle photograph of Red Lotus on 29 October 2010 appears very dark blue and red. Rosanoski questions whether lighting accounts for this, or whether the blue had changed; a photograph dated 20 March 2011 may indicate a darker sky blue, though the light was possibly murky.
No exclusive fleet-wide use or unrecorded corporate equivalence is asserted.
