If a colour blind female marries a man whose mother was also colour blind, what are the chances of her progeny having colour blindness?

Mother - Colourblind (X^CX^C) Father - Colourblind (X^CY) (A male progeny receives X chromosome from the mother. Since mother is colourblind, son is also colourblind).
X^CX^C - X^CX^C - X^CY - X^CY – F1 Generation
100% progeny will be colour blind.
