History

FED-STD-595, 595A, and 595B

Federal Standard 595 is the color description and communication system developed in 1956 by the United States government. Its origins reach back to

paradigm, providing for much more flexibility and wider range of applications. Each color in the Federal Standard 595 range is identified by a five-digit code. The colors in the standard have no official names, just numbers. The initial standard FED-STD-595 issued in March 1956 contained 358 colors. Revision A issued in January 1968 counted 437 colors. Revision B Change 1 from January 1994 counted 611 colors.

FED-STD-595C

Federal Standard 595C was published January 16, 2008. No previous colors were removed. Thirty-nine new colors were added for a total of 650 colors. On July 31, 2008 595C Change Order 1 was published, changing the numbers of eight of the colors added in revision C. The revision C master reference list of colors provides all available reference information for these colors, including

As before, all color matching must still be done via color reference chips. 595C Change Order 1 made a fundamental mistake by changing the designation number of existing, published colors. This can lead to considerable confusion when a color is called out by contract. Previous revisions had only added colors, so a color chosen out of 595A would still be accurate if the producer used a 595B fan deck in any of its revisions. Many prime contractors, such as L3, require the Federal Standard 595 paint chips used for inspection purposes be replaced every two years.
