Purple Statements

George and Maria using Purple Declarations in the original PC game

The Purple Declaration makes its first appearance in the 8th game, Twilight of the Golden Witch. Part of the eighth game is a murder mystery set by Bernkastel, in which Battler is required to sieve through the reports of all the surviving individuals on the island in order to find the culprit.

Any character can use Purple Declarations, which possess the same standing as the Red Truth; however, only the culprit can lie while using the Purple Declaration.

Along with other elements of the final mystery (master keys which disappear after a servant's death, unopenable windows, the unambiguous dismissal of Kanon's true nature after Shannon's death), this goes in hand with Bernkastel simply viewing the Rokkenjima mystery as an intellectual game, rather than a story in its own right.

Purple declarations are also used by Beatrice to set up a choice for Ange at the very end of the game, due to their ambiguous nature. Later it is also used in the spin off manga Forgery of the Purple logic .
