Subtle shifts in color within a handmade rug, often visible as horizontal bands across the field. They arise because successive dye batchesA single batch of dye, together with the yarn colored with it, all of which takes the same shade. Natural dyes are made in small artisanal batches, and when one runs out the replacement cannot be matched exactly, so yarn from different lots differs slightly in tone. In a finished rug the difference shows as the color shifts known as abrash, which is read as a sign of hand dyeing, whereas a perfectly flat, uniform color suggests synthetic dyes and machine making. never match exactly, because differences in the woolA natural animal fiber used for the pile, and in some rugs also the foundation, of high-quality rugs. It is durable, resilient, stain resistant and flame resistant, feels soft and cushioned underfoot, insulates against cold, and takes up dye readily and holds it for many years. It also traps dust particles, which helps reduce allergic reactions. Quality depends above all on where the sheep graze: high-elevation pastures and good feed give thicker, oilier wool, with Manchester, New Zealand and Ghazni wools the best-known prized examples. Early-spring shearing and hand spinning (finer, softer thread than machine spinning) improve it further, while thin, dry wool from dead sheep goes into cheaper rugs.'s fat and oil content make colors change unevenly with age, and, in cream areas woven from undyed woolWool left in its natural fleece colors, with no dye applied, so its shades run only through white, cream, brown, gray and black. Weavers combine white and black wool to reach these tones, which is how natural Gabbeh rugs, usually on a cream ground, get their palette. Many cream grounds in Persian and Oriental rugs also contain undyed wool; these areas can show slight variations of tone that shift as the rug ages, which is normal and not a defect., because the fiber changes tone as it ages. Abrash often grows more distinct with age, so in an older rug it counts as a sign of natural dyes and hand production rather than a fault, while a newer rug is still checked for even color. Machine-made and some new hand-knottedA rug construction in which the weaver ties each knot of wool or silk pile yarn by hand around adjacent warp threads on a loom, then runs a weft through the row and beats it down. The cut knot ends form the pile, the warps and wefts form the foundation, and the warp ends become the fringe. A rug can take months or even years, and the work leaves subtle irregularities: patterns not perfectly symmetrical, opposite edges a few inches different in length, an uneven fringe. Authentic Persian, Oriental and Turkish rugs are hand-knotted, unlike hand-tufted rugs (sometimes sold as “handmade”) and machine-made ones, whose backs feel stiff and evenly aligned. rugs imitate it on purpose.
Dye that has migrated from one colored area of a rug into the neighboring areas, for example after a professional wash or after a liquid spill that was not properly dealt with. Older rugs that have been washed several times are checked for it in particular. A rug with no color run commands the best price, while a significant run is a serious flaw that can rule a rug out at inspection. It is damage, unlike abrashSubtle shifts in color within a handmade rug, often visible as horizontal bands across the field.

The root of the madder plant (Rubia tinctorum), a natural red dye and the source of the terracotta tones in Persian and Oriental rugs.

Early-spring shearing and hand spinning (finer, softer thread than machine spinning) improve it further, while thin, dry wool from dead sheep goes into cheaper rugs., bonding to its natural lanolinThe natural wax that coats wool fibers and serves as the fleece’s own protection, waterproofing it. Wool from sheep raised at higher elevations is thicker and oilier ("fatty"), and a warm, slightly oily hand is a quick sign of real wool. In a carpet, the lanolin that remains repels liquids, so spills bead on the surface for a few moments instead of soaking in, one reason wool resists spills and soil. Hand spinning preserves it, while repeated harsh chemical cleaning strips it away, so gentle washing is recommended.. Slight shade variations within one color area, known as abrashSubtle shifts in color within a handmade rug, often visible as horizontal bands across the field. They arise because successive dye batches never match exactly, because differences in the wool's fat and oil content make colors change unevenly with age, and, in cream areas woven from undyed wool, because the fiber changes tone as it ages.

Weavers, above all tribal weavers, often prepare them from local plants and other natural resources of the region, which helps give each region its characteristic tones; madder rootThe root of the madder plant (Rubia tinctorum), a natural red dye and the source of the terracotta tones in Persian and Oriental rugs.

(terracotta reds), indigo (blues), walnut husks (browns) and pomegranate rindThe outer skin of the pomegranate fruit, a plant dyestuff used for the yellows in naturally dyed rugs, alongside madder root for reds, indigo for blues and walnut husks for browns. (yellows) are typical dyestuffs. Because dye is made in small artisanal batches, shades differ slightly from batch to batch, producing abrashSubtle shifts in color within a handmade rug, often visible as horizontal bands across the field.

Machine-made and some new hand-knotted rugs imitate it on purpose.. Natural dyes are prized for rich, harmonious, mellow color that fades gently and evenly with age and bleeds little on a damp cloth, though a rug may combine mostly natural dyes with a few synthetic ones.
The lightening of a rug's colors after long exposure to direct sunlight, most noticeable when one part of the rug sat in a sunny window patch while the rest stayed in shade, leaving that area visibly paler. Natural dyes soften with age in any case, but patchy fading counts as a condition flaw and is not the same as abrashSubtle shifts in color within a handmade rug, often visible as horizontal bands across the field.

Curtains or blinds at peak hours, UV-filtering film, a piece of fabric laid over an exposed patch and occasional rotation of the rug limit it; a rug sunned outdoors to dry should not have its face left long in strong sun.

Various techniques for coloring carpet yarns, including beck dyeing (immersion in dye baths), continuous dyeing (application after tufting), space dyeing (multiple colors on a single yarn), and solution dyeing (color added to liquid polymer before extrusion). Each method offers different benefits for colorfastness, pattern capabilities, and environmental impact. In hand-knottedA rug construction in which the weaver ties each knot of wool or silk pile yarn by hand around adjacent warp threads on a loom, then runs a weft through the row and beats it down.

A traditional method of dyeing carpet yarn in which loose skeins (loops) of already spun, plied yarn are immersed in dye baths before the yarn is knotted or woven into the rug.
