'Blue' in the Bible

There were fair hangings of white and green and blue, fixed with cords of purple and the best linen to silver rings and pillars of polished stone: the seats were of gold and silver on a floor of red and white and yellow and black stone.

And Mordecai went out from before the king, dressed in king-like robes of blue and white, and with a great crown of gold and clothing of purple and the best linen: and all the town of Shushan gave loud cries of joy.
