St. Rose of Lima who was a contemporary and close friend of the mulatto St. Martin de Porres. Both of them were Third Order Dominicans and apparently the color of the garment for Third Order Dominicans at that time was a dark green, at least according to a good number of the images seen of them and many images of St. Rose of Lima have her holding the crucifix. (I hope the beautiful statue did not originate with Santeria!)
