most other units, including cavalry, except in India where drab coloured garments were introduced in 1848 and worn increasingly from 1857 on. Until 1873 the other ranks of most infantry regiments wore tunics in madder red. In that year the brighter shade of scarlet was adopted, having previously been limited to officers, sergeants and all ranks of certain regiments of cavalry. General issue of full dress uniforms ceased at the start of the First World War. The Household Division resumed wearing their scarlet and blue full dress in 1920, but for the remainder of the Army it was only worn by regimental bands, or else on certain limited social or ceremonial occasions (an example of the latter was the 1937 Coronation when mounted detachments from participating cavalry regiments were issued with full dress uniforms for the occasion). The reason for not generally reintroducing the distinctive full dress between the wars was primarily financial, as the scarlet cloth required expensive red cochineal dye. Not all Full Dress uniforms were (or are) scarlet. Historically, the great bulk of the British Army wore red or scarlet (with the Royal Artillery distinctive in blue). In the early nineteenth century, the success of élite Hungarian Hussars and Polish Lancers inspired the creation of similar units in other European armies, which also adopted their highly-distinctive forms of dress; in the British Army, these light cavalry uniforms were mostly dark blue. At the same time, the formation of regiments of Riflemen (who had always worn dark green rather than red, for reasons of camouflage) led to the full-dress use of 'Rifle green' uniforms in Rifle regiments. Line Infantry regiments though invariably wore scarlet, as did heavy cavalry (with the exception of the Royal Horse Guards ('The Blues') and the 6th Dragoon Guards). Khaki In January 1902, the British army adopted a universal khaki uniform for home service wear, the Service Dress, after experience with lighter khaki drill in India and South Africa. The traditional scarlet, blue and green uniforms were retained for full dress and off duty "walking out dress" wear. Details of these colourful uniforms varied greatly between regiments and branches of the army. The early use of camouflage in the form of plain khaki reflected the exigencies of colonial war and the freedom allowed, and taken, by many of the officers who fought it. The adoption of khaki for active service resulted from the development
