US Navy & Marine Corps WW2 Camouflage (1942–1944) – Early War Paint Guide

The early years of World War II forced the US Navy and Marine Corps to abandon pre-war visibility-focused finishes and move toward operational camouflage that prioritized survival. Between 1942 and 1944, this transition produced one of the most recognizable—but also misunderstood—paint schemes in aviation history: the Non-Specular Light Gray / Blue Gray scheme.

This guide breaks it down practically—what the real colors were, how they behaved, and most importantly, how to replicate them correctly on a model without guesswork.

The Shift to Combat Camouflage (1940–1942)

On December 30, 1940, the Bureau of Aeronautics (BuAer) officially standardized a new finish for carrier-based aircraft: Non-Specular Light Gray overall. This marked the end of bright pre-war schemes like aluminum and yellow wings, which had become liabilities in combat conditions.

Shortly after, a two-tone camouflage was introduced:

• Upper surfaces: Non-Specular Blue Gray
• Undersides: Non-Specular Light Gray

By mid-1941, this became standard across the fleet.

Real-World Application – Why No Two Aircraft Look the Same

Here’s the truth most guides skip: there was zero consistency.

Paint was applied freehand, often on carriers, under pressure. That led to:

• Soft, uneven demarcation lines
• Variations in tone between squadrons
• Field improvisations (especially in the Pacific)
• Odd details like cowling tips painted differently

Examples:

• Early F4U Corsair had Blue Gray even under folding wing sections
• F4F Wildcat kept Light Gray undersides due to wing folding design
• Some SBD Dauntless aircraft had mismatched nose sections

If your model looks “too clean” or perfectly masked, it’s probably wrong.

The M-485 Specification – The Truth Behind the Colors

Both colors originated from M-485 specification (Dec 1940):

• Non-Specular Light Gray
• Non-Specular Blue Gray (added later in M-485a)

Important clarification:
The commonly referenced “M-495” is incorrect—it’s a long-standing typo that spread across publications.

Color Analysis & FS Equivalents

Non-Specular Light Gray

• Tone: Light warm gray (slightly beige/gold tint)
• Closest FS: FS 36440
• Visual behavior: Often appears lighter in photos due to lighting and weathering

Non-Specular Blue Gray

This is where things get messy.

There were multiple variations:

1. Early version – lighter, more blue, heavily fades
2. Later version – darker, more gray, more stable
3. Possible transitional variant (rarely confirmed)

• Closest FS approximation: FS 35189 (approximate only)
• Real behavior: Extreme fading in Pacific sun → chalky, washed-out look

Bottom line:
If your Blue Gray looks slightly “off”, you’re probably closer to reality than someone using a perfect swatch.

Weathering – The Key to Realism

If you ignore this, your model will look fake.

Real aircraft showed:

• Heavy sun bleaching (especially upper surfaces)
• Patchy repainting
• Salt wear and streaking
• High contrast fading between panels

Pro tip:
Start darker → fade unevenly → add variation panel by panel.

Modeling Paint Guide (AK, Tamiya, Vallejo, MRP)

NS Light Gray (FS 36440 equivalent)

• AK Real Colors – RC222
• Tamiya – XF-19 (lightened slightly)
• Vallejo – 71.050
• MRP – MRP-98

NS Blue Gray

No perfect match exists. Choose based on effect:

• AK Real Colors – RC261 (faded look)
• Colourcoats – accurate but light
• Model Master – more balanced
• MRP – closer to fresh paint

Tamiya mix (recommended):

• XF-18 + White (2:1)
  → Adjust until slightly desaturated

Transition to Three-Tone Scheme (1943–1944)

By 1943, the Navy realized the Blue Gray scheme wasn’t enough.

This led to the famous three-tone camouflage:

• Sea Blue (ANA 607) – upper surfaces
• Intermediate Blue (ANA 608) – mid sections
• Insignia White (ANA 601) – undersides

This wasn’t just visual—it improved concealment against sea + sky.

ANA Color Breakdown (For Late Early-War Builds)

Insignia White (ANA 601)

• Warmer tone than FS 17875
• Slight ivory tint

Intermediate Blue (ANA 608)

• Lighter than FS 35164
• Needs lightening in scale models

Sea Blue (ANA 607)

• Deep navy blue
• FS equivalent: FS 35042

Important:
Differences between ANA 607 and ANA 623 are minimal in scale—focus on contrast, not a theory.
