From the Transition page, you can set the duration of different smooth transitions.
The transition is the time when Iris goes between day and night mode for example.
The longer the transition the more smooth the colors will change to more orange and red or too bright screen.
Some people like instant transition why others prefer the transition to be several hours.
From here you can set it to whatever value you like.
