Abstract
A coated string for a stringed device which includes a coating applied to the surface of the string. The coating includes a base layer bonded to the surface of the string and an at least partially transparent low-friction top coat applied to the base layer. The base layer includes heat activated pigments that change color when heated above a color shifting temperature. In one embodiment, the color of the pigment in one area contrasts with the color of the pigment in an adjacent area without otherwise affecting the low-friction surface of the coating. The areas of different color created in locations along the length of the low-friction coated string.
