In 1977 "Scillonian III" went into service with her hull and superstructure painted white, her crane, funnel davits and masts were buff (yellow) without further markings. Some time after "Gry Maritha" was acquired, "Scillonian III"'s funnel and crane were painted blue to closer match the colours of the other ship, despite the Gry Maritha being a lighter colour blue with a white superstructure. For two seasons after the change of schedule post 1990, the lower half of her hull was painted dark blue with the upper half and superstructure, remaining white. The funnel was painted blue and white striped with a house flag, painted on the sides in the white stripe. The crane, davits and masts were painted blue.
