What is the color motif of St. Anne...the mother of Mary the mother of Jesus Christ?

Answer 1

Traditionally, the Roman Catholic Church uses baby blue to represent Mary and Anne. We Orthodox don't use color representations in ikonography the way the Church of Rome does.

Answer 2

According to Wikipedia, "In Western iconography, Anne may be recognised by her depiction in red robe and green mantle often holding a book." Another web link, also listed below, shows Anne reading a book to Mary. Anne is wearing a green mantle and red robe. She also appears to be wearing a blue apron for good measure.
