The hex color #234b78, also known as Chathams Blue, presents some accessibility challenges, especially when used as a background color for text. Due to its relatively low luminance, it requires careful consideration of contrast ratios. For text to be legible and meet WCAG (Web Content Accessibility Guidelines) standards, a light color must be used. Using a dark color on #234b78 will likely fail accessibility checks. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text (14pt bold or 18pt regular). Tools such as WebAIM's contrast checker can help ensure sufficient contrast. In user interface design, ensure that interactive elements such as buttons and links are clearly distinguishable against this background to provide a good user experience for individuals with visual impairments. Using it for decorative elements generally poses less of an accessibility risk.
