Who sold purple in the book of Acts in the Bible?

(Acts 16:14, 15) 14 And a woman named Lydʹi·a, a seller of purple from the city of Thy·a·tiʹra and a worshipper of God, was listening, and Jehovah opened her heart wide to pay attention to the things Paul was saying. 15 Now when she and her household got baptized, she urged us: "If you have considered me to be faithful to Jehovah, come and stay at my house." And she just made us come.
