Which factor is NOT typically considered in story arc development?

In story arc development, essential elements include character backstories, the inciting incident, climax, and resolution. Each of these elements plays a crucial role in shaping the narrative and guiding the audience through the emotional and plot-driven journey of the story.

Character backstory provides essential context for understanding characters’ motivations and behaviors. The inciting incident serves as a catalyst that propels the story into motion, establishing the main conflict that will unfold. The climax represents the peak of tension and conflict in the narrative, followed by the resolution, which provides closure to the story's main conflicts and ties up subplots.

Color grading, while an important aspect of filmmaking, particularly in visual storytelling, does not directly influence the narrative arc. It pertains to the visual aesthetic and mood of a film rather than the structural elements that develop the story's plot and character progression. Thus, it stands apart from the critical components that contribute to story arc development.
