Intro The Federal Standard Color System, now officially SAE AMS-STD-595 – Colors used in Government Procurement, is the United States Federal Standard for colors, issued by SAE. The standard is also widely referred to as AMS-STD-595, AMS-595 or other similar names. This color standard supersedes the old standard of FED-STD-595c and is now owned by SAE.

History Federal Standard 595 was established in 1956 by the United States government as the official color description and communication system. This system’s origins can be traced back to World War II. There were issues providing color specifications to contractors for military equipment. This system gave each color a unique five-digit code. It also established a color matching standard. FED-STD-595c was then published January 16, 2008. This established new colors and reference lists. As of February 14, 2017, FED-STD-595 was cancelled and superseded by SAE AMS-STD-595, “Colors Used in Government Procurement.” This is the authoritative standard regarding the regulation and consistency of color of items produced for government use. This new standard defines a color index system used by, but not limited to, government activities in a format suitable for color identification, color selection, color matching and quality control inspection. It also describes the designation and use of color media that is available to conduct these activities. The standard colors are all represented by a 5-digit sequence of numbers. AMS-STD-595 defines this color system for government activities. You may obtain the colors via single color chip, color deck (which includes all standard colors) or complete color chip set. As before, all color matching must still be done via color reference chips. Each color chip measures 3” x 5” and is supplied in a protective envelope. These chips are suitable for matching quality control inspection purposes and should be used in government procurement processes. There is also a fan deck available that showcases all 654 colors on 66 leaves. However, these are only to be used for general color representation only. They are not for matching quality control inspection. These products can be purchased officially through only one company, SAE International.

Government Compliance Color chips shall be used for color matching and control of items produced for government use. ONLY color chips marked “AMS-STD-595” shall be used as reference material for this new standard. Color matching shall be done by comparing CIE L*a*b color coordinates obtained from spectrophotometric analysis of the item produced for government use and the applicable color chip. SAE International also offers a $175 Color Examination Service to verify color compliance. Upon receiving a part or substrate from a customer, the sample will be measured using a Hunter UltraScan VIS, Diffuse Sphere 8 degree geometry spectrophometer. The results will be compared against the AMS-STD-595A standard. A comprehensive report will be supplied with the results. Many prime contractors, require the AMS-STD-595 paint chips used for inspection purposes to be replaced every two years. This is to account for color degradation over time and fading. If chips are not replaced, there is a risk of non-compliance.

Popular Colors The ten most frequently used colors from this standard are: -	AMS-STD-595A/20150 -	AMS-STD-595A/17925 -	AMS-STD-595A/37030 -	AMS-STD-595A/34094 -	AMS-STD-595A/37038 -	AMS-STD-595A/20220 -	AMS-STD-595A/33446 -	AMS-STD-595A/17875 -	AMS-STD-595A/20180 -	AMS-STD-595A/27038
