The color #1A4D68, also known as Chathams Blue, presents some accessibility challenges, primarily due to its relatively low lightness value. When used as a background color, it requires careful consideration of the foreground text color to ensure sufficient contrast. According to WCAG (Web Content Accessibility Guidelines), the contrast ratio between the text and background should be at least 4.5:1 for normal text and 3:1 for large text to meet Level AA compliance. For enhanced accessibility (Level AAA), these ratios increase to 7:1 and 4.5:1 respectively. Using a light text color like white or a very pale yellow can help achieve an acceptable contrast ratio. Tools like WebAIM's Contrast Checker can be invaluable in verifying compliance. Additionally, avoid using this color for essential UI elements or controls without proper contrast, as it can be difficult for users with visual impairments to perceive them clearly.
