dyeing

This term refers specifically to the chemical process of permeating a material with color. It is distinct from painting, where color is applied to the surface, and staining, which often refers to wood or biological samples. In industrial contexts, it carries a technical connotation involving chemistry, temperature control, and material science.

Care must be taken to distinguish this word from "dying," which refers to the end of life. While they are homophones in most dialects, the inclusion of the "e" is critical to maintain the meaning of color application. In professional textile and fashion industries, the term is used both as a noun for the process and as an attributive adjective to describe machinery or techniques.
