Well, certainly not in Ultra-Marine, however, it is not impossible that the dead-works could have been completely painted in this light copper-oxide based blue that Koedek has chosen. I have a loose theory that if the Royal Louis was originally painted all-white (Hyatt’s 1677 account), as flagship of the Mediterranean fleet, then perhaps SR was painted all-blue, as representative of the Atlantic fleet.
I have no textual basis to support this, but it is curious that Vary would represent the ship in these colors, unless there were some basis for it. What is known for sure is that the French always painted the dead-works (usually ventre-de-biche) because they were fastened with iron. Only the live works were tree-nailed.
Whatever the reality may have been, I do find it to be a striking choice.
