The mother of the bride is wearing a black gown What color should the grooms mother wear. the bridesmaids will be in candy apple?

The mother of the bride is definitely defying tradition by wearing black but this is the 21st century and there are lots of black/white theme weddings. The mother of the groom could wear the traditional beige or champagne to coordinate with the mother's choice of color. I am not sure what "candy apple" means. Is that green? If so, then she could choose a color more in line with the bridesmaids' dresses and wear lime, jade, hunter green or sage. If it candy apple is red, then the MOG could choose red, burgundy, wine, cinnamon.
