The Blue and the Gray

The Blue and the Gray

Illustrations of uniforms worn by Union and Confederate soldiers during the American Civil War.

The Civil War was, of course, a conflict between the Blue and the Gray. Actually, the color of the Confederate uniform was butternut, a light brown color.  The Union at the start of the war had myriad colors and styles, including Zouaves, cadet gray, and a mix of light and dark blue.  

After First Manassas, it became clear to both sides that identifying friend vs. foe was going to be crucial.  A universal uniform recognizable at first glance became needed. Some distinction as to branch of service was preferable, but the color of the clothes had to be immediately distinguishable. Why did the Union ultimately choose dark blue and the South light gray? 

Confederate Uniforms

At the start of the war, Confederate soldiers wore clothes from home and homespun. When cloth became scarce, the principal source of Confederate uniforms was captured Union uniforms.

The dark blue uniforms were boiled in a solution with walnut hulls, acorns, and lye. The resulting color was light tan, which the southerners called “butternut.” Weathered and faded gray uniforms also took on a light brownish appearance.

Gray was chosen for Confederate uniforms because gray dye could be made relatively cheaply.

Also, the standard uniform color of state militias was a shade of cadet gray, which is not suitable for combat wear, as it gives away the position of the individual easily from its bright blue-gray tones. Generals needn’t worry about this, so they wore beautiful gray uniforms that they purchased on their own.

Although it is often believed that gray uniforms became less prevalent in the Confederate army as the war went on, the opposite is true. In 1863, the Confederacy began purchasing pre-made uniforms from manufacturers in England and Ireland. Peter Tait & Company of Ireland was one of the main uniform makers whose products continued to make their way through the Union blockade.

American infantry had worn dark blue coats since the Revolutionary War, to separate them from the Redcoats. In the Mexican War, pale blue pants supplemented the coats. With mass production necessary for the Civil War, everything became dark blue. The blue dye was called Barlows indigo blue and before the mass production of cheap chemical dyes was perfected in Prussia in the late 19th century, natural indigo, was more expensive than gray dyes. 

Ironically, most indigo production was in the south; this caused the union to briefly resort to logwood dyes that immediately changed to brown reacting to sunlight. This is a lot of preserved uniforms have brown thread, as they continued to use logwood for dying thread as well other cheaper materials.

These dyes were too difficult to make in the South in large quantities, given limitations in resources. Instead, darker blue-gray became Confederate gray due to its availability through the blockade.

When the war began, volunteer militias created unique uniforms to make themselves appear stylish. 

Moreover, some northern militias developed very fancy red coats and pants to simulate the famous Zouave fighters from North Africa. These elite fighters wore elaborate uniforms with tassels, and fought in a non-traditional manner. Consequently, many Zouave units adopted fighting styles akin to light infantry: open formations, prone firing and reloading, and movement at double time. But as the war continued, these units disappeared and became regular army units.

Other special units with distinctive uniforms included: Berdan’s sharpshooters wore green uniforms with matte buttons (to prevent glare); the 39th New York Infantry called the Garibaldi Guard wore puffy red shirts like Italian soldiers; and the New York 79th called the Highland Guard wore plaid clothes and cap to simulate Scottish Highlanders.
