The first introduction of drab general uniform was by the British Corps of Guides in India in 1848. Initially the drab uniform was specially imported from England, with one of the reasons being to "make them invisible in a land of dust". However, when a larger quantity was required the army improvised, using a local dye to produce uniform locally. This type of drab uniform soon became known as khaki (Urdu for dusty, soil-coloured) by the Indian soldiers, and was of a similar colour to a local dress of cotton coloured with the mazari palm. The example was followed by other British units during the mutiny of 1857, dying their white drill uniforms to inconspicuous tones with mud, tea, coffee or coloured inks. The resulting hue varied from dark or slate grey through light brown to off-white, or sometimes even lavender. This improvised measure gradually became widespread among the troops stationed in India and North-West Frontier, and sometimes among the troops campaigning on the African continent.
