Stage directions are very significant in plays and scripts. They add context to the play and can also help to set the scene. Stage directions can add connotations to the play that may not have been as clear before. For example, in An Inspector Calls, when the ‘lighting turns pink’ this infers that the birlings could be wearing ‘rose tinted glasses’. This further implies that when they are wearing these glasses, they do not see the real world, but when they take them off, they realise that they are not perfect and are not powerful enough to not care about anything serious that happens.
Just did the test I this hope it helps someone in the future!
