The hex color #0548AF, also known as Cobalt, presents some accessibility challenges, especially when used for text or interactive elements. Its relatively low lightness value of approximately 24% means that it requires a very light foreground color to meet WCAG (Web Content Accessibility Guidelines) standards for contrast. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text to ensure readability for users with visual impairments. When using #0548AF as a background, consider pairing it with white or very light shades of gray to provide sufficient contrast.

Careful attention to color contrast is crucial to make web content accessible and inclusive for all users, including those with low vision or color blindness. Proper testing with accessibility tools is highly recommended.
