Until later on in the century dyes were primitive and different batches of uniforms worn by the same unit might present differing shades, especially after exposure to rain and sun. The white uniforms popular amongst many armies through the 18th and early 19th centuries soiled easily and had to be pipeclayed to retain any semblance of cleanliness. Green as worn by Jäger and Rifle regiments proved particularly prone to fading until suitable chemical dyes were devised in the 1890s. British soldiers were known for their striking red clothing (hence the name "Redcoats"). This was actually a fairly dull shade of madder red until the general adoption of scarlet for tunics in the 1870s.
