The hex color #0f3a89, also known as Congress Blue, presents some accessibility challenges, particularly in text-based applications. Its relatively low luminance value necessitates careful consideration of contrast ratios when paired with foreground colors. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal-sized text and 3:1 for large text to ensure readability for users with visual impairments.

Tools like online contrast checkers can be invaluable in assessing compliance. Furthermore, avoid using this color for crucial interactive elements like buttons or links without adequate visual cues, as users may struggle to identify them. Consider providing alternative styling options or high-contrast themes to enhance accessibility for all users.
