Feileadh Mor tartan as camouflage?

[Tobus]

But, I agree with figheadair, that for the most part in the tactics of the 17th-19th centuries did not require camouflaged kit, so the comments supposedly made about tartan being used as camouflage was probably meant to be derogatory, not complimentary.

The OP's question, though, wasn't about military uniforms or tactics. It was about hunting/stalking, sleeping in the open, and hiding. Not by uniformed soldiers, but by average civilian Highlanders.

I would tend to think that camouflage would be a natural benefit of tartans made with natural dyes. The Highlands do have a lot of colour in certain times of the year, and even bright tartans might blend in. As to whether they purposefully made their tartans with this in mind, though, I wot not.
