Yellow & Red laces
I remember from my youth when the skinhead movement started I was too young to hang in a pub so I hung around outside pubs with the punks and skunks, a skunk is a half punk half skinhead and are mostly Indians or blacks and not racist and into the western world (i.e) no religion and no politics the reason punks and skunks were Mowhaks & Moheicans was because the Mowhawk and Mohehcans fought unitl almost extict against the Imperial monarchal colonlial system so our generation adpated the Indian dress coden to display systemised contempt and when laces were pointed out to us, yellow laces in black doc martens were known to be anti Pakistani and red laces in black martin's were known to be anti Asian and so on (etc) it was a terrible time with lots of racial cinflict, communtity centres, resurantes and take away were always targetted.
In an unrelated term, nickname skins were taken from the term native American skins as in animal skins worn by the tribal warrior braves and during the sixty years Indian wars in an Indian confederacy created by six main tribes to drive the pilgrims, settlers and US cavalry out of America(s) through these days they symbolize 100% Indian tribalism.
