About colors in rugs

In small fragments of very old Chinese rugs, and in copies of them, natural colored   wools  and  hair  are used in combination or in varying tones of the same color.    

Simple floral or symbolic objects are worked in a bleached white, while the body of the  rug is of unbleached wool.    

Camel's hair   is  varied   with  dark  wool  and   several shades of tan are so mingled as to show lines of solid colors surrounding a figured field.
