Hello hazegry, the colour schemr that Moran gave me for mine is as follows. I don't know if the older tugs are the same I should think they are.
Hull above the water including the bulwarks, Moran Hull green
Inside of Bulwarks Black
hull below the waterline, Red oxide anti fouling
Main casing and wheelhouse Moran casing Red
Main deck Moran deck red
texas or bridge deck and the wheelgouse roof Light gray
all hanrails around decks Light gray
Grabrails around casings Black
deck overhangs and visor White
And all paint exept the anti fouling is Gloss.
Moran towage were kind enough to send me a complete set of plans for the Mirium as well as a set of paint samples of their In house colours A brilliant company to deal with.
All the best george.
