The Red Truth is a fact that can be presented by the Witch Side without any evidence or proof to support it. But, while undeniable, it can have multiple interpretations. The multiple interpretations mark a large foothold for the Human Side to attack; therefore, the Red Truth must be used with care. Conversely, a refusal to validate a statement in Red invokes another Devil's Proof; a lack of validation won't prove a statement's truth but can't disprove its falsehood. If someone attempts to lie using the Red Truth, they will choke on the words that they're trying to say.
