"American paint schemes" Topic

Could someone give me an any idea of typical paint schemes for my American 1812 squadron, please.

Black with white gunports.

The American 1812 Great Lakes Squadron USS Niagra

The simple answer is: Black hull with white trim and stripe. The longer and more correct answer is: well, it's kind of complicated.
See here for info on the Constitution: PDF link

As for the United States, there is certainly some debate about that. There is a discussion about it here, but it does mostly focus on Constitution: link
The famous painting of US versus Macedonian by Thomas Birch in 1813 shows the US with a black hull and two small red stripes, one above and one below the gunports.

Finally, one source (and I don't remember which one) says the President in 1815 had the white stripe below the line of the gunports. So there is certainly plenty of room for customization of your fleet of US frigates.

In that era – there were no regulations in place in any navy that I know of.

Usually, it was up to the Captain of the ship, or maybe a Commodore or Admiral or… the whims of the tides and winds etc…

. . . not to mention the cost and availability of paint. Ochre was cheap and widely available, hence its popularity. About that time, it became possible to manufacture white pigment economically and in large quantities, so it increasingly replaced ochre, especially in the American navy.

A single broad strake across the gunports was very typical, but a narrow strake below and/or above was also used. The painting of Niagara, above, was modelled after the 1913 reconstruction. During the war, she (and her sister, Lawrence) was all black – not a typical paint scheme, but then they were built in a hurry, in a remote backwoods yard, and only intended to be used once.
