I haven't looked at the kit for a good many years, but I'm fairly confident that the colors are generally correct. Revell, however, has a habit of making the color callouts on its instructions kind of sketchy. The "barbor pole" carvings between the windows should, for instance, be painted in red and white diagonal stripes.
Gold was not nearly as common a color in early-nineteenth-century ship decoration as it was in the seventeenth and early eighteenth centuries. Gold leaf existed, of course, but it usually was applied only in small areas. (H.M.S.
Victory, for instance, has scarcely any gold paint on her. It's confined to the figurehead, some of the carvings at the top of the transom, and some details of the canopies over the entry ports.) As I recall, Revell suggests painting most of the head rails at the bow and the scrollwork between them gold. That
may be right, but I'd be more inclined to paint most of those parts yellow ochre, and reserve the gold for the most elaborate of the carvings.
The truth of the matter is that we aren't sure exactly what colors the
Constitution was painted. A good deal of research has been done in the past few years, but there are still quite a few gaps. The Revell 1/96 kit represents her as she appeared in 1814. (Some folks have questioned some of the details, but I think the Revell rendition - which is based on a set of plans commissioned back in the early sixties by the Smithsonian - is pretty close.) In that year it's extremely likely that the stripe on her hull was yellow ochre rather than white (though it had been white in 1812). I think the insides of the bulwarks probably were green and the lower masts were black; white actually doesn't seem to have been a popular color during the War of 1812.
There are, of course, quite a lot of books about the
Constitution. For modelers the best may be the most recent:
Old Ironsides, by Thomas Gilmer. The color illustrations, by the excellent marine artists William Gilkerson and Tom Freeman, are worth careful study. Those gentlemen know what they're doing.
Hope this helps a little. Good luck.
