How does the author use color in the novel, The Way Back?

The author uses colors as a form of symbolism in this novel. Lilith always wears white, which is usually associated with innocence and purity. In this case, it identifies Lilith as the leader of a group of women known as the Lileen, the Sisters, or the War Cats. Those women wear gray which could be symbolic of the mixture of Lilith's white and black, which is typically associated with evil. Yehuda Leib's scarf is red, which is often associated with blood as a life force. The scarf has some of Avimelekh's blood on it. Mottke accepts the red color from the scarf as payment for Bluma to ride the ferry from the Far Country to Tupik.
