Color is a powerful tool in design that instantly communicates meaning. Utilizing it as a visual signifier can guide users' attention to key elements like buttons. For instance, the color red is often associated with alerts or destructive actions. It serves as a clear signal for features such as error messages or delete functions.

By aligning color cues with user expectations, you create a more intuitive interface that helps users navigate more effortlessly. Just remember, the colors should complement the overall design and meet accessibility standards for optimal user experience.
