Which component is NOT typically part of information architecture?

The correct answer highlights that color theory application is typically not considered a fundamental component of information architecture. Information architecture primarily focuses on organizing, structuring, and labeling content effectively to make it easier for users to find information and complete tasks. Key aspects include navigation systems that help users move through the site or application, content organization that determines how information is grouped and presented, and user interaction analysis, which examines how users engage with content to enhance usability.

In contrast, color theory pertains more to visual design, addressing how color is used in layout and aesthetics to invoke emotional responses or improve readability. While color can certainly affect the user experience, it does not directly relate to the functional aspects of how information is structured and accessed within an interface, which is the primary focus of information architecture.
