The color #1D4E7E, a deep shade of blue known as Chathams Blue, presents some accessibility challenges, primarily concerning text legibility. When used as a background, sufficient contrast with text is crucial. White text (e.g., #FFFFFF) generally provides good contrast, achieving WCAG 2.0 Level AA compliance at a minimum. However, lighter shades of gray or yellow might also work, depending on the specific hue and saturation. Avoid using this color with darker text colors (e.g., black or dark grays) as the contrast will be insufficient, making it difficult for users, especially those with visual impairments, to read comfortably. Careful consideration of font size and weight can also improve legibility. It's always recommended to test color combinations with accessibility tools to ensure compliance with accessibility standards. The contrast ratio should be at least 4.5:1 for normal text and 3:1 for large text.
