Modern industrialized Berber carpets are distinguished by a loop pile construction type that gives a similar appearance to the distinct knot of traditionally woven Berber carpets. The modern carpets usually contain small flecks of dark colour on lighter shades of background colours resembling a natural undyed version of the traditional carpets. They generally consist of a plain colour mix with no pattern, and are relatively cheap and durable. Popular for areas with significantly heavy use such as offices. The distinctive knot texture and appearance of traditional hand-woven Berber carpets today are generally woven in brightly coloured designs that are different from other oriental rugs.
