“ Violet , the amethyst, signified love and truth; or, passion and suffering. Hence it is the color often worn by the martyrs. In some instances our Saviour, after his resurrection, is habited in a violet, instead of a blue mantle. The Virgin also wears violet after the crucifixion. Mary Magdalene, who as patron saint wears the red robe, as penitent wears violet and blue, the colors of sorrow and of constancy. In the devotional representation of her by Timoteo della Vite, she wears red and green, the colors of love and hope.
“ Gray , the color of ashes, signified mourning, humility, and innocence accused; hence adopted as the dress of the Franciscans (the Gray Friars); but it has since been changed for a dark rusty brown.
