The hex color #1D507B, also known as Chathams Blue, presents certain accessibility considerations, particularly in web design. Its relatively low luminance value may pose challenges for users with visual impairments. When using this color for text, it's crucial to ensure sufficient contrast against the background. A contrast ratio of at least 4.5:1 is recommended for normal-sized text and 3:1 for large text (14pt bold or 18pt regular) to meet WCAG AA standards. For WCAG AAA compliance, even higher contrast ratios are necessary. Providing alternative color schemes or allowing users to customize colors can further enhance accessibility.

Careful consideration of font size and weight can also improve readability when using #1D507B.
