The hex color #204A78, also known as Chathams Blue, presents some accessibility challenges, especially when used as a background color for text. Its relatively low luminance means that text needs to be a light color to provide sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. When using #204A78, ensure that the foreground text color meets these contrast requirements to ensure readability for users with visual impairments. Tools like WebAIM's Contrast Checker can be helpful in determining appropriate color pairings. Considering alternative, lighter shades of blue or using a white or very light gray text color can improve accessibility significantly. Also, avoid using this color for critical interactive elements without clear visual cues.
