The invention provides a novel class of natural red azaphilone pigments: cavernamines and their hydroxyl-derivatives; as well as the organge/yellow precursor cavernine. Additionally, methods for their production by fermentation using a fungal strain belonging to the species Aspergillus cavernicola, is provided; and further the use of the novel pigments as a colouring agent for food items and/or non-food items, and for cosmetics. The cavernamine pigments have the structure of Formula I or II, the hydroxyl-derivative of said cavernamine pigment has the structure of Formula III: Cavernine pigments having the structure of Formula IV or V are precursors f the cavernamine pigments I-III above.
