Abstract

A cable in accordance with the invention includes at least one core filament having a visually distinctive appearance; and a jacket, wrapped around at least a portion of said core filament. The jacket is adapted to change its opacity in response to tensile stress, thereby modulating the visibility of the core filament in relation to such stress. As a result, the overall appearance of the cable responds to stress, by changing at least one of chroma, hue, or value (visual appearance) quantifiably in response to tension.
