Color purple speaks of life conception. Human embryo looks purple to a darker color of blue.
Evangelistic mental is most potent. Signs and wonders often follow the evangelistic message delivered by a truly anointed for that task evangelist. There are different evangelistic callings and anointings, which are often characterized by zeal and passion. Unlike the pastors evangelists are on the go, some of them are even supernaturally transported by God's Spirit. Such an evangelist was Philip.
[Acts 8:26-29] But an angel of the Lord spoke to Philip saying, “Get up and go south to the road that descends from Jerusalem to Gaza.” (This is a desert road.)  So he got up and went; and there was an Ethiopian eunuch, a court official of Candace, queen of the Ethiopians, who was in charge of all her treasure; and he had come to Jerusalem to worship,  and he was returning and sitting in his chariot, and was reading the prophet Isaiah.  Then the Spirit said to Philip, “Go up and join this chariot.”
We see that God's angel is that same Spirit who spoke to Philip  to join the Ethiopian official who was reading the Book of Isaiah. After the Ethiopian believed [30-40] and was baptized God's Spirit snatched Philip.  But Philip found himself at Azotus, and as he passed through he kept preaching the gospel to all the cities until he came to Caesarea.
That is the fastest way to travel.
Evangelists should always work with apostles and pastors, for apostles create churches and pastors look after the sheep.
