This approach supports consistent and accessible theming aligned with your design guidelines. Show full answer Show less ## Using Color Variables for Mobile Icons Mobile icons include a **Set appearance** section where you can specify the **FontColorVariable** style. By assigning a color variable here, you select from colors defined in the UX Theme Properties \[sysuxthemeproperty\] table, ensuring consistency across your app's UI. This method simplifies managing icon colors and helps maintain compliance with accessibility standards. ## Color Palettes and Their Purpose Two main color palettes are provided to guide your color selections: * **Alert Color Palette:** Designed to highlight important statuses, states, and tasks. Use these colors to convey specific meanings (e.g., critical, warning, info) rather than for decorative purposes. * **Grouped Color Palette:** Reflects industry or line-of-business conventions. These colors help users associate elements with a particular context while maintaining consistency within the app. Both palettes offer multiple variations including accessible options that improve usability, especially when icons lack text. Using accessible color options is recommended to enhance navigability for all users. ## Color Variable Naming and Options Each color in the palettes is available as multiple variable options for flexibility: * **Mobile Variables:** e.g., `alert--critical-2`, `alert--critical-3`, and an accessible option `alert--critical-4`. * **Web Variables:** Prefixed with `--now-color`, such as `--now-coloralert--critical-2`, `--now-coloralert--critical-3`, and accessible `--now-coloralert--critical-4`. This naming convention applies consistently across all alert and grouped colors (e.g., high, warning, info, blue, green, purple). Selecting the right variable ensures your icons integrate seamlessly with your theme and maintain visual clarity and compliance. ## Practical Benefits for ServiceNow Customers * **Consistent Theming:** Easily align icon colors with your organization's branding and UX theme. * **Improved Accessibility:** Use accessible color variants to enhance user experience, especially for visually impaired users. * **Simplified Configuration:** Use predefined variables rather than defining custom colors, reducing development effort and errors. * **Clear Visual Communication:** Apply alert colors to signify status and importance, and grouped colors to indicate business context effectively.
