Forum:Red Eyes Darkness Dragon special summoning?

The rulings say that Red Eyes Darkness Dragon cannot be special summoned from the graveyard at all. What if you have a Red Eyes Black Dragon on the field when you try to special summon the Red Eyes Darkness, so that its summoning condition is still met? Would you be able to special summon it from the graveyard in this manner or would it still be impossible to summon it from the graveyard?
