The color #04111A, a very dark, muted blue-charcoal, presents significant accessibility challenges. Its extremely low luminance results in very poor contrast against almost any background, particularly white or light colors. Text rendered in this color would be virtually unreadable for users with normal vision and completely inaccessible for individuals with low vision or color blindness. To ensure accessibility, it is crucial to avoid using #04111A for text or interactive elements unless paired with a very light or bright contrasting color that meets WCAG (Web Content Accessibility Guidelines) AA or AAA contrast ratios. Tools like contrast checkers can help determine if the color combination is sufficiently accessible. Considering alternative, lighter shades of blue or charcoal would significantly improve the user experience and inclusivity.
