The hex color #155083, also known as Chathams Blue, presents some accessibility challenges, particularly when used as a background color for text. Its relatively low luminance value means that it requires careful consideration of the foreground text color to ensure sufficient contrast. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text to meet AA compliance. When using #155083, a light text color such as white (#FFFFFF) or a very light shade of yellow or green would be necessary to achieve acceptable contrast. Tools like contrast checkers can help determine whether a specific color combination meets these standards. For users with visual impairments, including those with low vision or color blindness, adequate contrast is crucial for readability and overall usability. In situations where sufficient contrast cannot be achieved, alternative color choices should be explored to ensure inclusive design.
