  This article addresses the possibility of supporting the construction of
emotions in the participants of Interactive Digital Narratives (IDN) by means
of colours. The article uses goal models for expressing protostories. The core
of the article consists of the case study where two colour synes-thetes were
asked to choose colours for eight emotions. Thereafter the same synesthetes
were asked to choose colours for the emotions that support the attainment of
goals in the Cinderella narrative, which serves as an example protostory. The
article also discusses the perspectives for applying the method proposed by us
to using colours in constructing emotions by IDNs.
