Why the Union wore blue and the Confederacy gray during the Civil War
Historical records show that uniform colors played a significant role in identifying soldiers during the Civil War. The choice of color was not immediately clear-cut, as many Confederate soldiers initially wore uniforms that were similar to those of the US Army. The US Army had a long-established tradition of wearing a particular color, which dated back to the Revolutionary War era.
This color was still worn by many troops at the start of the Civil War in 1861. Further details about the evolution of uniform colors during this period are available from historical accounts, which provide insight into the complexities of the time.
