Could I just interject briefly to say, the correct spelling of the word that describes the 'British tan' colour of dusty brown with a hint of green in it, is "khaki", with an H, and pronounced "car-key".

The word originated in British India and comes from the Hindustani language and means "dust covered, earth coloured or like the soil." and was applied to describe the colour of British Army uniforms of the mid to late 19th Century (once we'd got rid of those silly Red Coats). the Hindustani word in turn, has it's root in the Persian word "khak", meaning soil.

The phrase "Kaki-pants" has a whole different meaning in British English.

Thank you. Apologies for the pedantic interruption, do carry on.
