Chinese rug coloring

Blue in Chinese rugs when combined with white  shows as varying  results as   does   the   mingling   of the   same colors  in   Chinese   porcelains.   

To   Chinese blues many names have been applied which obtain with more or less accuracy.

There is the indigo or deep strong blue found in the rugs of both Northern and Southern China, and the azure blue which is almost never found in rugs later than the eighteenth century.

Sapphire blue found in Kien-lung Chinese-Turkestan rugs is unlike the light blue of either earlier or later periods.

Silver blue appears in Peking rugs and grey blue in the products of Ning-hsi and the Northern provinces.
