International Orange (12797) is the wrong shade for CG red (12799).
From the USCG website:
When did the Coast Guard adopt the “slash” for its cutters, boats, and aircraft?
The design consists of a wide red bar forward of a narrow blue bar both canted at 64 degrees above the horizontal with the Coast Guard emblem superimposed. It was originally recommended in 1964 by the industrial design firm of Raymond Loewy/William Snaith, Incorporated and was adopted service-wide on 6 April 1967.
The color red used in the slash is Pantone 179.
The color blue used in the slash is Pantone 307
From the USCG Color and Coatings Manual:
Coast Guard Diagonal Stripes. The diagonal stripes are to be painted red (12199), white (17925),
and blue (15182).
The USCG Color and Coating Manual was updated in the year 200' That update replaced white (17875) with white (17925). White (19925) is a pure white; while white (17875) has a slight gray tinge.
