Union Blue is a rich, dark navy based on the iconic wool uniforms worn by Union soldiers during the American Civil War.

The Union Army’s choice of dark blue uniforms—known today as "Union Blue"—was based on a combination of tradition, practicality, symbolism, and existing supply chains:

1. Military Tradition

  • Dark blue was the standard color for the U.S. Army long before the Civil War, dating back to the Revolutionary War and solidified during the War of 1812.
  • The color was associated with discipline, professionalism, and loyalty, modeled after European military uniforms (particularly French and Prussian styles).

2. Preexisting Federal Stockpiles

  • When the Civil War began in 1861, the U.S. government already had large supplies of indigo-dyed blue wool uniforms.
  • Maintaining the blue color allowed for continuity and logistical efficiency, especially important in the early chaotic months of mobilization.

3. Visual and Tactical Reasoning

  • Blue contrasted well with the Confederates’ gray and butternut, which helped differentiate friend from foe on the battlefield (especially as uniforms became more standardized).
  • Dark blue was considered a less conspicuous alternative to bright reds used in older European uniforms, which had fallen out of favor as rifled firearms increased in accuracy.

4. Symbolism of Union & Unity

  • Blue had become symbolic of the United States federal government, and was used in flags, emblems, and navy uniforms.
  • Wearing dark blue reinforced the Union’s identity as the preservers of the United States, in contrast to the secessionist gray of the Confederacy.

While officers and enlisted men wore varying shades and styles (due to supply and local contractors), the iconic navy blue frock coat and kepi became a hallmark of Union imagery.

Edward R. ★★★★★

The matte finish lays down perfectly on kepis and doesn't come out shiny like some acrylics I've tried. It's a solid match for Union blue uniforms.

Michael ★★★★★

That deep navy is spot-on for Civil War uniforms—I used it on a Union officer's coat and kepi and the color reads as authentic next to my brass button details. It's thin enough to lay down smoothly over primer but covers well in two coats, no chalky residue.

Jason H. ★★★★★

The matte finish dries perfectly flat, so my 1/72 scale Union infantry look convincingly uniform without any sheen. It covers well in two thin coats and the deep navy is exactly what I needed for period-correct kepis.
