The colors of a rug are created by a variety of dye formulas and can be influenced by a final washing process. It is important to know the process to ensure longevity of color.

Natural dyes are derived from organic sources such as plants and even insects. The colors from these sources convey an earthy honesty in beautiful, lustrous tones. Modern synthetic dyes can create an infinite range of colors. These chrome dyes are stable, permanent and attractive. Many quality rugs are made with a mixture of natural and chromatic dyes.

The final washing process is necessary to cleanse the wool and enhance the colors. Quality rugs made with hand-spun, hand-dyed wool do not need an elaborate wash. A natural soap wash preserves the intrinsic qualities of a handcrafted rug and embellishes its antique appearance. The colors will remain "fast," maturing only slightly over decades.
