The hex color #004a9d, also known as Cobalt, presents some accessibility challenges. Its relatively low lightness value means it may not provide sufficient contrast against white backgrounds for users with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. When using Cobalt for text or important interface elements, it's essential to test the color contrast against the background color.

Consider using a lighter shade of blue or a different color altogether to ensure optimal readability and usability for all users. A proper color contrast is crucial for those with low vision or color blindness.
