The hex color #0F4A81, also known as Chathams Blue, presents specific accessibility considerations for web developers. Its relatively low luminance necessitates careful selection of foreground colors to ensure sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Using white text on a #0F4A81 background may provide adequate contrast, but it's crucial to verify this with accessibility testing tools. Darker shades of text against this background are likely to fail accessibility standards.

Providing alternative styling options, such as high-contrast modes, can further enhance accessibility for a wider range of users.
