Using this color for interactive elements like buttons or links requires a clear visual distinction upon hover or focus, to assist users navigating with keyboards or screen readers. Thorough testing with accessibility tools is crucial to ensure compliance and a positive user experience for individuals with visual impairments. Avoid pairing it with other dark colors, as this can further reduce contrast and accessibility.
