grisaille trompe l'oeil

colourful lizard and butterfly on trompe l'oeil grisaille mural

butterfly and lizard counterpoint

This type of effect where an illusionistic grisaille architecture is further developed by an additional layer of painted illusion dependent upon the first layer allows for colorful details to be added. These can provide counterpoint and lyrical elements to enter the work and are ludic in virtue of context.
