The hex color #0B1990, a deep ultramarine, presents specific accessibility challenges. Its low luminance value means it requires careful consideration when used as a text or background color. To ensure readability, it should be paired with light text colors, such as white or very pale shades of yellow or gray. Using this color for interactive elements like buttons or links necessitates clear visual cues, such as distinct borders or hover effects, to help users understand their functionality. Furthermore, avoid using this color for conveying important information without redundant cues, as users with visual impairments might struggle to differentiate it from darker shades. WCAG guidelines recommend a contrast ratio of at least 4.5:1 for standard text and 3:1 for large text against its background to meet accessibility standards. Tools are available to check the contrast ratio between colors to help developers comply with accessibility guidelines.
