The color #0A0B91, a deep ultramarine, presents accessibility challenges due to its low luminance. When used as a background color, it requires very light text to ensure sufficient contrast for readability, ideally achieving a contrast ratio of at least 4.5:1 as recommended by WCAG guidelines. Using it for text requires careful consideration of the background color; a light or white background is essential. Avoid pairing it with dark or similarly muted colors, as this can lead to poor visibility, especially for users with visual impairments. It's crucial to test color combinations with accessibility tools to ensure compliance and optimal user experience. Also avoid using this color for essential information or call to action buttons, as it may not be noticeable enough for some users. Consider using a more vibrant or contrasting color for important elements.
