The color #0B1191, a deep ultramarine, presents significant accessibility challenges, primarily due to its low luminance. When used as text, it requires a very light background to meet WCAG (Web Content Accessibility Guidelines) standards for contrast ratio. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text (14pt bold or 18pt regular). This deep blue shade might fail these criteria against many common background colors, potentially causing readability issues for users with visual impairments. Therefore, careful consideration should be given to the background color choice. Using tools to check color contrast is essential. Also avoid using this color for critical interactive elements without sufficient contrast, as it could be missed by users with low vision. Alternatives might involve using a lighter tint of blue or pairing it with high-contrast accent colors to enhance visibility.
