Red guess it gave Golden when Harry used it on Lord V? Usually red, only gold when it becomes Priore Incantartum.--22.214.171.124 19:11, April 4, 2010 (UTC) 126.96.36.199 19:46, April 4, 2010 (UTC) says: What Harry's wand spat at Voldemort was not Stupefy. It was an undescribed spell, one of Voldemort's own. It probably held more power than anything any wizard except for Voldemort and Dumbledore could manage. And it was flames, not a jet. Also, it's spelled Priori Incantatem and the moment it happens, it really isn't the original spell anymore, rather sort of an effect of a collision of magical energies and wizards' wills. He doesn't use stupefy on voldemor anyway its expelliarmus.
