'Blue' in the Bible

And now send me a man skilful to work in gold, and in silver, and in bronze, and in iron, and in purple and crimson and blue, and experienced in carving, besides the skilful men that are with me in Judah and in Jerusalem, whom David my father provided.

the son of a woman of the daughters of Dan, and whose father was a man of Tyre, experienced in working in gold, and in silver, in bronze, in iron, in stone, and in timber, in purple, in blue, and in byssus, and in crimson, and for doing any manner of engraving, and for inventing every device which shall be put to him, besides thy skilful men, and the skilful men of my lord David thy father.

And he made the veil of blue, and purple, and crimson, and byssus, and made cherubim upon it.
