I have several carrier models in my collection. Those that survived until later in the war did receive camouflage. Several ships were converted into carriers , especially after the loss of the main carrier force at the battle of Midway. The conversions included remodeling passenger liners (Hiyo and Junyo) and converting former submarine or seaplane tenders (Chiyoda, Zuiho, and Chitose). Deck markings varied, but usually included a red and white striped section that showed the start of the landing deck aft. Individual identification letters were used and their placement was not uniform.
