What is the purpose and/or meaning behind the specks of color that appear through tweed and few other woolen fabrics out there? I don't mean just the variances in color throughout the yarn, but the bright blue, green, yellow, and red bits. I don't suppose it's one of life's great mysteries that will help solve the world's plight, but I've always been curious. Any of the more informed out there have any ideas?


Not sure if this is better suited to the miscellaneous forum, but it deals with fabric used in kilts & kilt accessories, so I ran with it. If I am way off base, please have mercy as you pick up your torches and pitchforks.
