The hex color #0B0C8D, also known as Ultramarine, presents some accessibility challenges, primarily due to its dark hue. When used as a background color, it requires light-colored text to ensure sufficient contrast for readability. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Ultramarine may not meet these ratios with moderately dark text colors. Therefore, pairing it with white or very light shades of yellow or gray is crucial. Conversely, as a text color, #0B0C8D should be used sparingly on light backgrounds, and its contrast ratio should be carefully checked. Avoid using it for small text or essential interactive elements without proper contrast adjustments. Tools like contrast checkers can help determine compliance with accessibility standards, ensuring that content is usable for individuals with visual impairments. Implementing these considerations ensures inclusivity and a better user experience.
