"In the trade from India to the West, textiles were essential. Madras, pajama, and the Kashmir shawl travelled the route that, for the British, came to define richness or, by acronym, posh: Port Outward, Starboard Home. Khaki was derived from the yellow-saffron dust that inflected the naively white uniforms of the colonials and shrewdly became their regulation color. Even today, "khaki" is strictly a color in the United Kingdom and "chinos" designate the pants. The color and the cotton trousers made their voyage to France, England, America, and around the world, even arriving in one country a shade darker than another (notably the preference for a darker, salade-Nicoise-tinged khaki in France.)"
