The hex color #154986, also known as Chathams Blue, presents some accessibility challenges, particularly in text-based contexts. Its relatively low luminance value means that it requires careful consideration of contrast ratios when paired with other colors. According to WCAG guidelines, sufficient contrast is essential for users with visual impairments to perceive content effectively. When using #154986 as a background or text color, it's crucial to ensure a contrast ratio of at least 4.5:1 against normal-sized text and 3:1 against large text (14pt bold or 18pt regular) and user interface components. Lighter shades of yellows, whites, or light greens are generally recommended for text placed on a #154986 background to achieve adequate contrast. Tools like WebAIM's contrast checker can be invaluable in verifying compliance with accessibility standards. When used for interactive elements, providing additional visual cues like underlines or borders can further enhance usability for users with color vision deficiencies.
