Cut pile carpets sometimes show a shading effect that appears as light and dark patches due to different pile direction.

This effect can be exaggerated by such things as room lighting and certain types of traffic across the carpet.

Shading is a natural phenomenon which cannot be totally eliminated in the production process and is therefore not considered to be a manufacturing fault.

Shading explained

Shading is a term widely misunderstood by suppliers, retailers and consumers. In order that the benefits of purchasing a Brintons carpet with their unique guarantee can be fully appreciated, it is necessary to explain the nature of shading.

Basic definition of shading

Shading can be defined as a localised change in the appearance of a carpet brought about by pile tufts leaning in different directions. Areas of pile tufts leaning towards you will appear darker whereas pile tufts leaning away from you will appear lighter. This may give the appearance of a colour change which is in reality only an optical effect.

These effects can be temporary or permanent.

Temporary shading

This is localised shading effect, caused for example by footprints, which can be removed simply by brushing the carpet pile in the direction of its natural lay.

Permanent shading

This occurs in two forms:


Areas of permanent shading relating to foot traffic patterns within a location are referred to as tracking effects. Turning points in a room and doorways are susceptible to this form of predictable traffic induced shading.

Random shading

Areas of permanent shading that do not appear to be related to known traffic patterns are referred to as random shading effects. They vary in shape, size and position and are sometimes described pooling, although humidity, temperature, static electricity and other locational effects may have an influence.
