I say, if you prefer it, paint it. Ships of that era were often painted and repainted to the captain's or admiral's preference.
I have one question. What are you making the water from? I have built many ships in many bottles and now, I am at a loss as to the material for the water since my original stuff is no longer manufactured and I want something that needs no baking and does not shrink or fog up the inside of the bottle. Please show pics of your little wonder.
