Understanding U.S. Military Color Standards
"Military color standards were developed to ensure consistency across manufacturers, simplify logistics, and improve operational effectiveness. For the scale modeler, understanding these standards is essential for producing historically accurate replicas."
Introduction
More information on why Micro-Mark’s acrylic paint is the best representation of US Military model paint. One of the greatest challenges facing military modelers is determining what constitutes the "correct" color for a particular vehicle, aircraft, ship, or piece of equipment. Historical photographs often vary dramatically due to lighting, film type, aging, and reproduction quality. Museum restorations may incorporate modern paint systems, while surviving artifacts frequently exhibit decades of fading, oxidation, and weathering.
Fortunately, the United States military has relied upon a series of standardized color systems to ensure consistency among manufacturers and maintenance facilities. These standards evolved over more than a century as military technology advanced, beginning with Quartermaster specifications, expanding into the Army-Navy (ANA) system during World War II, progressing to the Federal Standard 595 series after the war, and ultimately transitioning to the Aerospace Material Specification (AMS) 595 standard used today.
Understanding these systems allows modelers to select historically appropriate colors while appreciating that operational conditions frequently produced acceptable variations from the published standards.
Why Color Standards Exist
Military equipment is produced by hundreds of contractors across multiple locations. Without standardized color specifications, each manufacturer would produce slightly different shades, creating inconsistencies in camouflage effectiveness, maintenance, and logistics.
Standardized colors provide several operational advantages:
- Consistent camouflage performance.
- Simplified procurement.
- Interchangeable replacement parts.
- Standardized maintenance procedures.
- Uniform appearance across production facilities.
- Improved identification of military equipment.
For scale modelers, these standards provide documented references that can be translated into commercially available hobby paints.

Federal Standard 595
Federal Standard 595 (FS 595) was introduced in 1956 by the U.S. General Services Administration (GSA) to create a unified color reference for government procurement. Rather than specifying paint chemistry, the standard defines the appearance of a color using physical reference chips.
An important distinction is that FS 595 specifies color only. It does not prescribe:
- Paint manufacturer
- Resin chemistry
- Pigment composition
- Application method
- Coating thickness
- Durability
Multiple paint manufacturers can therefore produce coatings that comply with the same FS designation while using different formulations.
Over the decades, FS 595 became the dominant color reference for:
- Army vehicles
- Navy ships
- Marine Corps equipment
- Air Force aircraft
- Missiles
- Ground support equipment
- Military facilities
Even after the introduction of AMS Standard 595, FS numbers remain deeply embedded within military documentation and the modeling community.
Understanding the FS Numbering System
Each Federal Standard color is identified by a five-digit number.
Example:
FS 34087
Each digit carries specific information.
How Federal Standard Numbers Are Organized

For example:
- FS 34087 = Flat Olive Green
- FS 36118 = Flat Gunship Gray
- FS 36375 = Flat Light Ghost Gray
- FS 16440 = Gloss Gull Gray
This numbering system allows experienced modelers to identify basic characteristics of a paint simply by reading its designation.
FS 595A, FS 595B, and FS 595C
As military requirements evolved, the Federal Standard underwent several revisions.
FS 595A
Released in the 1960s, FS 595A expanded the available color library while improving consistency between printed documentation and official color chips. Numerous aircraft and vehicle colors introduced during the Vietnam era first appeared in this revision.
FS 595B
FS 595B refined color tolerances and incorporated additional modern camouflage colors, particularly those used by NATO and late Cold War military equipment. The revision also improved manufacturing consistency among paint suppliers.
FS 595C
Published in 2008, FS 595C represented the final Federal Standard revision. Although relatively few colors changed, documentation became more comprehensive and reflected decades of military procurement experience.
Many modern hobby paint manufacturers—including Micro-Mark—continue to reference FS 595C because it remains familiar to modelers worldwide.
AMS Standard 595
In 2017, responsibility for maintaining federal color standards transitioned from the General Services Administration to SAE International.
The result was AMS Standard 595 (Aerospace Material Specification 595).
The transition was largely administrative. Existing Federal Standard color numbers remained unchanged, allowing military contractors and hobby manufacturers to continue using familiar designations.
Examples include:
- FS 34094
- FS 36118
- FS 36375
- FS 16440
Today, AMS 595 serves as the official color reference for many aerospace and defense applications while preserving compatibility with earlier Federal Standard documentation.
ANA Colors
Before Federal Standard 595, military aircraft relied on the Army-Navy (ANA) color system. Created during World War II, ANA colors standardized finishes across both Army Air Forces and U.S. Navy aircraft production.
Examples include:
- ANA 601 Insignia White
- ANA 603 Sea Gray
- ANA 607 Non-Specular Sea Blue
- ANA 611 Interior Green
- ANA 613 Olive Drab
Many later Federal Standard colors trace their origins directly to ANA specifications.
Army-Navy Aeronautical Standards
The ANA system represented one of the first truly joint military color programs.
It standardized:
- Exterior camouflage
- Interior finishes
- National insignia
- Recognition markings
- Aircraft primers
- Protective coatings
This standard significantly improved production efficiency during World War II, allowing multiple aircraft manufacturers to produce visually consistent aircraft despite enormous production volumes.
Quartermaster Standards
Before centralized federal color standards existed, the U.S. Army Quartermaster Corps established specifications for uniforms, equipment, leather goods, wagons, tents, and eventually early military vehicles.
Quartermaster specifications introduced iconic colors such as:
- Olive Drab No. 9
- Khaki
- Canvas Tan
- Wagon Green
- Field Brown
Although less precise than later systems, these standards laid the foundation for twentieth-century military camouflage.
MIL-SPEC Coatings
Color represents only one component of a military coating system. Military specifications (MIL-SPECs) define additional performance requirements, including:
- Corrosion resistance
- Chemical resistance
- Abrasion resistance
- Ultraviolet stability
- Salt fog resistance
- Fuel resistance
- Infrared signature reduction
- Radar absorption (for specialized coatings)
Examples include modern Chemical Agent Resistant Coatings (CARC), which provide both camouflage performance and protection against hazardous environments.
For modelers, understanding the intended finish—matte, satin, or gloss—is often just as important as matching the correct color.
Comparing U.S. Standards with RAL
Many military modelers also build German or NATO subjects, making it useful to compare U.S. Federal Standard colors with the German RAL system.
Unlike Federal Standard, RAL was developed primarily for industrial and architectural applications.
Although there is no exact one-to-one conversion, approximate comparisons are often sufficient for modeling purposes.
|
U.S. Standard |
Approximate RAL Equivalent |
|
FS 34079 Forest Green |
RAL 6003 Olive Green |
|
FS 36118 Gunship Gray |
RAL 7012 Basalt Gray |
|
FS 36375 Light Ghost Gray |
RAL 7035 Light Gray (approximate) |
|
FS 37038 Black |
RAL 9005 Jet Black |
These comparisons should always be treated as approximations rather than exact matches.
The Munsell Color System
The Munsell Color System provides a scientific method for describing color using three independent dimensions:
- Hue
- Value (lightness)
- Chroma (saturation)
Unlike Federal Standard numbers, which serve as catalog identifiers, Munsell notation describes how a color appears visually.
Museums, conservation laboratories, and restoration specialists frequently use Munsell notation because it enables objective communication of color characteristics independent of specific paint manufacturers.
RGB, HEX, and Digital Color Approximations
As digital design and online commerce have expanded, hobbyists increasingly encounter military colors represented by RGB and HEX values.
Examples include:
- Digital camouflage references
- Online paint conversion charts
- Website product pages
- CAD renderings
- Instruction manuals
However, digital values should be viewed only as visual approximations.
Computer monitors, smartphones, printers, and cameras all reproduce color differently due to calibration, color profiles, brightness settings, and display technologies. Consequently, no RGB or HEX value can substitute for an official Federal Standard or AMS color chip when historical accuracy is required.
Micro-Mark paint development should always be based on physical color standards and validated paint samples rather than digital representations alone.

Chapter Summary
Military color standards have evolved from simple Quartermaster specifications to sophisticated, internationally recognized systems used throughout the defense industry. While names such as Olive Drab, Haze Gray, and Interior Green are familiar to most modelers, understanding the underlying standards—Quartermaster, ANA, Federal Standard 595, and AMS 595—provides the historical context needed to reproduce military equipment accurately.
For scale modelers, these standards should be viewed as authoritative references rather than rigid absolutes. Manufacturing tolerances, operational wear, lighting, and weathering all contributed to natural variation in service. By combining documented standards with thoughtful interpretation, modelers can create finishes that are both historically accurate and visually convincing.
