I recall reading somewhere that insulation is usually extruded over the wire as the wire is pulled thru a die with the nominal diameter of the insulation. Because changing colors within one extruder is messy and wasteful, an extruder/die combination is devoted to one color or small group of colors. Insulation thickness variation results from the use of different dies for each color and the mfg variation inherent in the production of the dies. IOW, the insulation thickness variation is not directly related to color but is a result of production process variation in turn resulting from the decision to minimize color changes in the production equipment.
Looked for a link that references this but couldn't find it.
