'Purple' in the Bible

The king cried aloud to bring in the enchanters, the Chaldeans, and the soothsayers. The king spake and said to the wise men of Babylon, Whosoever shall read this writing, and show me the interpretation thereof, shall be clothed with purple, and have a chain of gold about his neck, and shall be the third ruler in the kingdom.

But I have heard of thee, that thou canst give interpretations, and dissolve doubts; now if thou canst read the writing, and make known to me the interpretation thereof, thou shalt be clothed with purple, and have a chain of gold about thy neck, and shalt be the third ruler in the kingdom.

Then commanded Belshazzar, and they clothed Daniel with purple, and put a chain of gold about his neck, and made proclamation concerning him, that he should be the third ruler in the kingdom.
