Cochineal Dyes?

[Bugbear]

Ok * sigh * my question got lost or ignored over in the white hose thread.

Were cochineal dyes used to make the rusty, red-brown colors sometimes seen on tartans "back in the day"?
Or was that color created or due to some other dye or process?

Some other process. Cochineal makes red-red.*



*Red-Red is a name of a Wilton brand gel color used for cakes and stuff. It tastes bitter, so Wilton developed No-Taste Red, which is not bitter.
