Why is someone displaying absolute loyalty said to be “true blue”?

With the slogan “a true covenantor wears true blue,” the Scottish Presbyterians adopted blue as their colour in the seventeenth century during their defense of their faith against Charles I. The instruction came from Numbers 15:38 in the scriptures, which tells the children of Israel to fringe the borders of their garments in ribbons of blue. Blue is a powerful symbol of Judaism and the national colour of Israel.
