Feileadh Mor tartan as camouflage?

[Sir William]

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.

You missed my point entirely, which was camouflage was not a common concept prior to the mid-19th century. Tartan may have provided that capability, but it was not the intent when the weaver the his dyes. He used what dyes he could obtain.
