Their light has become impure. Impure=negative. Light=positvity. Light+negativity=dark light. Like I clearly stated, dark light is a combination of those 2 things. So no I am right. Just because light has destructive powers too doesn't mean that denies what dark light it is. About where I read this, I already said it's called doing research to learn the proper name of a power/ability. If the very power or ability perfectly describes the power/ability shown, then that is the exact name to call that power/ability. I can ask you the very same on how Vali would have demonic light and same the same things you have said to me in the context of that subjext. Superpower wikia explains all powers and abilities. If this isn't dark light then Apophis does not have umbrakinesis etc.
