Don't rely on colour alone
Colour can help communicate information, but it should not be the only means of conveying information. For instance, use labels, patterns, icons, or text in conjunction with colours to provide additional context and clarity.
Identify interactive elements
Use different styles for interactive elements like links and buttons to help users identify them. Keep the styles and naming consistent throughout the application.
Provide clear navigation
Ensure clear and consistent navigation across your application and offer multiple ways to navigate, such as a search bar or site map. Provide orientation cues with breadcrumbs and clear headings.
