what is the meaning of the color red in the book The Red Badge of Courage by stephen crane?
Wound while in battle is symbol of bravery, hence the blood stain as proof or evidence.
Blood or more specifically a bullet wound.
In some ways Crane's style is ornate, as has been noted above, with profuse use of color and rampant metaphor in a way which was rare for his time. The blues and grays of the two sides of the American Civil War are often described as natural phenomena, swirling like clouds. Fleming's Regiment was a broken machine. In dialog, however, the style is earthy, written out to sound as close to the vernacular of the day as possible. This realism was later to inform many works but was relatively rare at the time.
