B303 is the original funnel. The ships’ original Irish-green livery changed in 1935 to black hulls and green funnels, B87, after repeated union black bans. Mitchell gives sea green. A narrow white funnel band, B89, appeared on Kuranda around 1960 and was broadened after the 1968 takeover. The original flag was green with a central vertical red band bearing an ornate white B. US Navy 1961 already shows a block B, while Rosanoski dates the later simplified B89 letter to the takeover.
Sid McGrath wore this final livery in its last months of service: a plum funnel and a white flag with green JB placed diagonally. The recorded plum is R179 G0 B45.
