When used as a background, it requires very light text (white or near-white) to ensure sufficient contrast for readability, meeting WCAG (Web Content Accessibility Guidelines) standards. A contrast ratio of at least 4.5:1 is recommended for normal-sized text and 3:1 for large text. Using this dark blue for text on a white background is highly discouraged due to insufficient contrast.

Furthermore, avoid using color alone to convey important information; supplement it with text or icons to cater to users with color blindness.
