Final answer:
The question refers to historical uses of color in warfare, not modern soldiers' personal use of dyes or bleaches. Examples include colored poison gases in WWI and the symbolic blue uniforms of USCT soldiers in the Civil War. Today, bleach is commonly used domestically, not by soldiers.
Step-by-step explanation:
The question "Soldiers use dyes, tints, or bleaches what color must they use?" seems to be related to historical practices rather than any direct use of such substances by soldiers today. Historically, soldiers did not typically use dyes, tints, or bleaches concerning their own appearances but may have encountered various colored substances during warfare.
For example, during World War I, soldiers were exposed to poison gases like chlorine gas, which had a greenish tint, and mustard gas, which could cause severe harm to skin and eyes. Moreover, troops in the American Civil War, such as the African American Soldiers in the United States Colored Troops (USCT), wore blue uniforms to symbolize their fight against slavery and wore these as a statement of liberation.
In modern contexts, soldiers' equipment and uniforms are often colored with camouflage patterns to blend into various environments, a far cry from the overt colors seen in earlier warfare. It is important to note that bleaches are typically used today in domestic settings, such as for laundry or stain removal, and are not used by soldiers for personal coloring purposes.
