What is the color of a schooner boat?

It can be any color the owner wants. Boats are generally black or white. This is traditional. In northern climes boats were painted black to absorb heat, and in southern climes they were white to reflect heat. This doesn't matter much anymore now that most boats are fiberglass or metal. With wood boats it is still an important consideration because wood shrinks or expands depending on how much moisture is in the wood and temperature has lot to do with that. But if you go to a marina you will see boats that are red, blue, yellow, green, brown and other colors. I have even seen pink and purple boats.
