It seems to me that this is a "shades of grey" sort of thing. A 16oz wool kilt made in the traditional technique is the white and Utilikilts with its low waist, narrow apron etc is black. USAk semi-traditional is on the whit side of grey and sport kilt is on the black side of grey. From what I understand, solid color (i.e. saffron) kilts made in a traditional manner is...well...traditional. Please correct me if my thinking is wrong.
