As I believe I have mentioned at times, I have chosen to use pre-war (or transitioning to war) color schemes rather than the boring gray gray gray of wartime painting.
Because my eyes are not the best and I wish to be able to easily distinguish the vessels of various nations.
As can be seen by the photo above (click on it for a larger image), I have painted the Japanese ships with their black hulls and funnels, and white superstructure and turrets. The Russian ships have dark cinnamon brown hulls, khaki superstructure, ochre funnels and dark gray turrets . . . which approximates the reports of the Pacific Squadrons early in the war.
By the way, I do know that the Russian Pacific Squadron had white hulls pre-war, but I'm reserving that for the US "Great White Fleet" which I'll eventually have.
For I have gone through all of the Pre-Dreadnought navies that I might eventually want to own and planned the basic paint scheme of each so that all will be unique unto themselves.
