When designing storyboards, why is it beneficial to use different colors?

Using different colors in storyboards is beneficial as it helps to distinguish between user input and program output. This visual differentiation allows developers and designers to easily identify the flow of information in the program, clarifying which components are interactive elements (user input) and which are responses or results generated by the program (output).

Clearly showcasing this distinction can significantly enhance the understanding of how the application will function and how users will interact with it. It supports effective communication among team members and ensures that everyone involved has a shared understanding of the program’s design and user experience.

Each of the other options, while they may offer value in specific contexts, do not capture this essential clarity in interaction design that color-coding provides.
