On January 5, 1943
the Navy issued a Specification SR-2c, for the application of the Tri-Color
paint scheme.
On January 30, 1943
the Navy issued a directive on how to mix the required colors from paint in
stock to help speed up this change and reduce the waste of old paint.

Now you have the new
paint colors made by different paint manufacturers and all of the combinations
of mixed paint from existing stocks being applied in the factories on new
aircraft.
Plus you also have
all of the colors that were mixed and applied to aircraft in the field.
I believe this may
have created a variety of shades of N.S. Sea Blue.
The Photos;
The first three
photos show examples of N.S. Sea Blue and Intermediate Blue painted with Model
Master Paint on models.
Photo # 4 is the
Color Hue Degree Chart.
Photos # 5 and 6 are
Don's Color Chips for N.S. Sea Blue.
Photo # 7 is a Model
Master Chip for N.S. Sea Blue.
Photo # 8 and 9 are
Don's Color Chips for Intermediate Blue.
Photo # 10 is a
Model Master Chip for Intermediate Blue.
Photos # 11 thru 16
are Don's Color Chips for the colors used to field mix N.S. Sea Blue and
Intermediate Blue.
All of the color
chips were measured using Adobe Photoshop 5.5 color picker to get the Hue,
Saturation, and Brightness.
I mix MM 1718 FS
35042 N.S. Sea Blue and 1723 FS 36118 Gunship Gray to reduce the saturation of
blue to get the paint to more closely match Don's Color Paint Chip.
