Atlantis uses the following schemes.
Eumelos sporting the standard peacetime light grey scheme with black masts used by most of the fleet.
Memnon sporting her light/dark grey splinter pattern in the current South American conflict.
The CL Brencis uses similar colours except the entire hull up to main deck is dark grey while the upperworks are painted light grey. The CLAA Zerberus has the same scheme but with a false bow wave added.
The CV Alioth the CL Acestus, CLAA Danaus and several DD's use a similar scheme to the Chilean pacific wartime scheme (U.S. measure 11). In the case of Alioth ocean grey is used above the main deck. Slower support ships will often sport false bow waves and in wartime will, for the Atlantic theatre use a variation of the Brencis scheme with the bow and stern pained light grey to create the illusion of a shorter ship, while in the Pacific sea blue is used.
Atlantis paints the bulk of its coastal gunboats a dark grey while MTB's can be either dark grey or in the case of Caribbean stationed vessels a camo of light grey, dark grey and ocean grey.
Decks are usually painted the same colour as the hull (except wood decks) while some upper decks, usually on small bridge structures, are a dark tan.
Colombia uses a standard grey for the Caribbean theatre and a sea blue scheme for the Pacific, decks pained the same colour.
Both Colombia and Atlantis paint river gunboats in a dark green sometimes with light green camo painted to an unspecified pattern which leads to creative paint jobs.
Turkey uses light grey as a standard colour while in the Sea of Marmara and Black Sea dark grey is used. Training ships will often have funnels painted yellow with black tops.
