Glengarry Colors???

[mgc]

Glengarry colors of WW1 highland battalions and regiments? I know the Argyles wore the dk blue with red & white checking only, while Scottish Rifles wore rifle green and Black Watch wore the plain dk blue (almost black). The London Scottish I believe wore gray (?). How about others such as the 10th Kings or Tyneside Scottish? Did pipers in some battalions/regiments wear different headgear? I know many wore different badges. Maybe we could come up with a comprehensive list. Thanks!
