The term that defines a material specification that includes coloring and texturing is "Finish." In the context of materials, particularly in locksmithing or related fields, a finish refers to the surface treatment applied to a material, which can significantly influence both its appearance and performance. Finishes can include various techniques and materials that alter the color, texture, and overall aesthetic quality of the surface. This is important not only for aesthetic appeal but also for protective purposes, helping to resist corrosion, abrasion, and other environmental factors.

The other terms in the choices do not pertain to the specifications of color and texture. "Hub" typically refers to a central part of a mechanism, "Mortise" relates to a specific type of joint or recess for a lock cylinder, and "Edge-Bore" is a term related to drilling or creating openings in materials, which does not encompass the broader aspects of finish characteristics. Understanding these distinctions clarifies why "Finish" is the appropriate answer in the context of material specifications.
