A tracer stripe is used when color coding is accomplished by more than one stripe on the same wire; the first or widest is the base stripe, and the others, usually narrower, are the tracer stripes.
A tracer stripe is part of a color-coding scheme in which a wire is marked with more than one stripe to identify it. The first, or widest, stripe is called the base stripe, and the additional, usually narrower, stripes are the tracer stripes. By combining a base color with one or more tracer colors, this method greatly expands the number of distinct identifications available, allowing many conductors in a cable to be told apart.
Because relying on solid colors alone limits the number of distinguishable conductors, adding tracer stripes to base colors multiplies the available combinations. This is essential in multi-conductor cable where many wires must be uniquely identified for correct connection.
In commercial and industrial cable, tracer stripes support the identification of conductors in multi-conductor and multi-pair constructions. Recognizing the term helps in understanding how wires are color-coded for correct termination.

At Windy City Wire, an understanding of identification methods, including tracer stripes, reflects a focus on cable that is easy to install and terminate correctly. Recognizing how base and tracer stripes expand color coding helps illustrate how conductors are distinguished in multi-conductor cable.
