The hex color #0A0C8E, also known as Ultramarine, presents specific accessibility challenges, particularly concerning color contrast. When used as a background color, it necessitates very light text (white or near-white) to ensure sufficient contrast for readability, meeting WCAG (Web Content Accessibility Guidelines) standards. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. It's crucial to avoid pairing this color with darker shades or colors with similar luminance, as this can make content illegible for users, especially those with visual impairments. Careful consideration should be given to users with color blindness, who may struggle to distinguish content if relying solely on color to convey information. Using supplementary cues like text labels or icons can significantly improve accessibility. Proper testing with accessibility tools is vital before deployment.
