The hex color #0B1790, a deep shade of ultramarine, presents several accessibility considerations. Its low luminance value means it requires careful pairing with text colors to ensure sufficient contrast for readability. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text. Using white (#FFFFFF) text on a #0B1790 background provides good contrast and meets accessibility standards. However, lighter shades of gray or other colors may not provide enough contrast and should be carefully evaluated. This color might not be suitable for users with visual impairments or color blindness if contrast is not properly addressed. When using this color for interactive elements like buttons or links, sufficient visual cues beyond color alone should be provided to ensure usability for all users.
