The hex color #0A172A, also known as Black Pearl, presents significant accessibility challenges, especially in text-based applications. Its extremely low luminance value means that it requires very light text (ideally white or near-white) to ensure sufficient contrast for readability. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal-sized text and 3:1 for large text. Black Pearl often fails to meet these criteria when paired with darker shades, potentially causing visual strain for users, particularly those with visual impairments. Careful consideration should be given to the background and foreground color pairings, with thorough testing conducted using accessibility evaluation tools to confirm compliance. Using this color as a background for large blocks of text should be avoided unless paired with a very bright color. Also using it for small icons or other user interface elements may not pass accessibility requirements and should be avoided.
