Which files need to be updated to change the style and color of pages in SailPoint?

To change the style and color of pages in SailPoint, updating iiq-custom.css and ui-custom.css is the correct approach.

The iiq-custom.css file allows for custom styles to be applied directly to the IdentityIQ user interface, enabling tailored changes that align with specific branding or design requirements. This file is typically where you would define custom CSS rules that override the default styles applied by the application.

Similarly, ui-custom.css is a file dedicated to user interface components, allowing for modifications to the layout and visual aspects of the application. By utilizing these two specific files, you ensure that the changes made are effective and maintainable, as they are designed explicitly for such customizations in SailPoint environments.

In contrast, other options may refer to stylesheets that are not specific to SailPoint's customization framework, thus not applicable in this scenario.
