The color #0D40A7, a deep shade of cobalt, presents some accessibility considerations. Its low lightness value means that sufficient contrast is crucial when pairing it with text or other interactive elements. According to WCAG guidelines, 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) against its background. Lighter shades of yellow, white, or very light gray would be appropriate choices to ensure readability and usability.

Providing alternative text descriptions for images using this color is also good practice.
