When switching an application to use a warmer color scheme, which two rules must be modified? (Select two)

Modifying the skin rule is essential when switching an application to a warmer color scheme because the skin rule defines the visual appearance and styling of the application. It encompasses elements such as colors, fonts, and layout, which directly impact the aesthetic qualities that users experience. Therefore, adjustments made in the skin rule will ensure that the new warmer color palette is consistently applied across all user interface components.

In addition to the skin rule, the section rule should also be modified. Section rules determine how particular sections of the user interface are rendered, including the layout and styling aspects. By updating the section rules in conjunction with the skin rule, you ensure that the warmer color scheme is effectively applied to all relevant sections of the application, leading to a cohesive and visually appealing user experience. This alignment is crucial for achieving the desired look and feel throughout the entire application.

The flow action rule, while related to elements of user interaction, does not control overall color schemes or visual styles; rather, it primarily impacts the actions and transitions users take within the application. The application rule defines the foundational aspects of the application but does not directly manage visual styling either. Thus, focusing on the skin and section rules is key for implementing a new color scheme effectively.
