The Navy essentially had 4 paint schemes during the war. Early in the war was medium blue on top and a very light gray below.
Mid-war, starting at the same time the star with bar with the red surround was adopted, the Pacific and Atlantic adopted different schemes. The Pacific aircraft had three tone, dark blue, medium blue, and white in the bottom. The exact pattern of these colors varied from one plane to the next. In the Atlantic, it was gray-blue upper and white below.
In mid-1944, they adopted the all over glossy dark blue. The night fighters carried this scheme before then, but it was adopted fleet wide. It took a while for all aircraft to change schemes. Some were still in tri-color in early 1945.
The F6F-5 was introduced just after the color change was, so virtually all of them were over all glossy dark blue.
Note, I didn't use the official names for the colors. I'm too lazy to look them up.
