The color #154F86, also known as Chathams Blue, presents some accessibility challenges, particularly concerning color contrast. When used as a background color, it requires very light text to ensure sufficient contrast for readability, ideally achieving a contrast ratio of at least 4.5:1 as recommended by WCAG guidelines for Level AA compliance. Larger text sizes (14pt bold or 18pt regular) can allow for slightly darker text while still meeting accessibility standards. It's crucial to test color combinations with accessibility tools to verify compliance, especially for users with visual impairments. Using this color for essential interface elements or links should be avoided unless paired with high-contrast text or visual cues to guarantee usability for all users. Careful consideration of text size, font weight, and surrounding colors is necessary to maximize accessibility.
