"Note: The color mentioned as Graded Tone Areas is described by Grumman as a gradual transition from Non Specular Sea Blue to Non Specular White. This was probably achieved by mixing both colors together in specific quantities. When examining photographs, in some cases one can see this demarcation of color quite evidently. Other photos seem to show this as in intermediate Blue."
