- Symbolism of colors
The colors of the genuine oriental carpets find their origin from the plants, natural minerals, and animals. Hence, these colors are termed as natural colors. From plants, sources like indigo, saffron and henna leaves provide colors. The juice of magenta snail, blood as well as insects, are used in animals category to derive colors for the carpets. Minerals like copper vitriol, ferric oxide, and iron vitriol are used to extract colors for the genuine carpets too.
However, in the ear 1826 when aniline dye was invented, newer methods came up for manufacturing colored carpets. In Europe, the color industry manufactured a better-quality version of this dye, and hence, aniline dye was used alongside natural colors in the East.
Over the years, the dye has displaced the use of natural dyes. This is because there has been a significant increase in the demand for oriental carpets, especially in the past four decades. Therefore, manufacturing oriental carpets by using natural dyes has become an expensive affair. One can't rely on the natural colors for catering to this big demand. These natural colors are used only by nomads these days for the carpets. The antique varieties of carpets also utilize natural colors only.
The ink utilized in the coloring process is not trivial. Hence, large quantities might be required. Example, 1 kg of coloration might be required for about 4kg of wool. The result of ink coloration will vary according to the hardness of water as well as wool quality.
Nomads generally make use of the colors that are available to them easily. However, as per the lifestyles of the tribes, only a mere quantity of wool can be dyed with limited coloration substance. This results in the irregular color intensity of the carpet. Thus, this irregularity in the forms of lines or other textures is called ‘Abrash.' These deviations actually look lovely if they do not arise glaringly.
