'Blue' in the Bible

There were hangings of white, green, and blue material, fastened with cords of fine linen and purple to silver rings and marble pillars. The couches were of gold and silver, on a pavement of red, white, yellow, and black marble.

Mordecai went out of the presence of the king in royal clothing of blue and white, and with a great crown of gold, and with a robe of fine linen and purple; and the city of Susa shouted and was glad.
