When used as a foreground color for text, it requires careful pairing with a background color to ensure sufficient contrast for readability.

When used for interactive elements like buttons or links, ensure sufficient visual cues, such as a change in color or a clear border, on hover or focus states to aid usability for all users, including those with visual impairments and those using assistive technologies.
