Spain has a long history of fabric production dating back to the 8th century. The conquest of Spain by the Moors in 711 lead to major developments in textile production. With improvements in irrigarion techniques for agriculture and the introduction of seraculture (silk worms and silk), Spain's textile industry grew to major importance. Cotton, silk and linen became important exports. Silk textiles were luxury goods, often woven into gold brocades. After the final Christian conquest of Granada, and expulsion of the remaining Muslims, the silk industry virtually disappeared.
Wool was another important product. It was often worn by the peasant class. Merino sheep were introduced to Spain during the thirteenth century.
Indigo (Indigofera) a native plant of India was imported for blues. It has been grown in the British Isles since 1193.
Kermes produced scarlets - Al-Andalus was famous for its production and export of "qirmiz" (kermes) which is an insect similar to the New World cochineal that produces brilliant reds. This red dyestuff was prepared from the dried bodies of various female scale insects of the genus Kermes. The French kermès,is short for alkermès, from the Arabic al-qirmiz, probably from Sanskrit kRmi-ja-.
Madder - True madder (Rubia tinctorum), also called turkey red, is a dye plant native to S. Europe. The herb's long, fleshy root was the principal source of various brilliant red dye pigments
Saffron produced a high-quality, expensive yellow dye from its orange stigmas. A member of the Iris family, (Crocus sativus) this purple or white flower with orange stigmas was native to the Asia Minor. One ounce of saffrom powder requires stigmas from about 4000 flowers. The Moors introduced it into Spain in 711 A.D.
Safflower produced red or yellow, depending on how it's processed. It is a thistlelike Eurasian plant (Carthamus tinctorius) of the composite family, having heads of orange flowers that yield a dyestuff.
Woad (Isatis tinctoria) was cultivated in al-Andalus for its leaves that yielded a blue dye. (Sky-blue)
Other colors from that time included rose to browns, mulberry - a greyish to deep purple, greens, black and grey.
