The color #1B1880, also known as Deep Koamaru, presents significant accessibility challenges, especially in text-based contexts. Its extremely low lightness value (around 9%) results in very poor contrast against standard white backgrounds, failing WCAG's AAA and AA standards. Therefore, it's crucial to use this color cautiously. To ensure readability and accessibility, pair it with very light colors like whites (#FFFFFF), off-whites (#FAFAFA), or very light grays. Avoid using it for essential interactive elements such as links or buttons without careful contrast consideration. When using this dark shade, provide sufficient visual cues and redundant methods, like underlining links. Also, consider users with impaired vision who might require higher contrast for content consumption. Adequate color contrast enhances user experience and inclusivity.
