I've heard from several different sources that before the invention of modern dyes pre-Culloden highlanders would use natural dyes (obviously, no modern dyes) from plants and their surroundings to get a very natural and earthy color to their tartans. They would use this as camouflage while sleeping ing the brush, hunting, or hiding from the British.

Is this true? Do tartans actually serve as effective camouflage? Has anyone tested, tried or use them as such? If so, which tartan, and how did you use it? Pictures would be great!

Thanks, Derek.
