Its dark hue results in a relatively low contrast ratio when paired with lighter text. It's crucial to ensure that the contrast between text and background meets WCAG (Web Content Accessibility Guidelines) standards, specifically a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Using online contrast checkers is advisable to verify compliance. When used for interactive elements, supplementary visual cues are recommended, such as underlines for links or distinct hover states for buttons, to improve usability for users with visual impairments. Avoid using this color as the sole indicator of functionality. It's also important to test the color on various screen types and under different lighting conditions to confirm that it remains legible and accessible across diverse user environments. Meaningful text and labels should not rely solely on color to convey information.
