The color #111188, also known as Ultramarine, presents some accessibility challenges, particularly when used as text on a white background. Its low luminance value (approximately 0.03) results in very poor contrast, failing WCAG (Web Content Accessibility Guidelines) standards for both AA and AAA levels. To ensure readability and usability for all users, especially those with visual impairments, it's crucial to use this color with caution. Pairing it with a very light color such as white or light yellow for text is strongly discouraged. Consider using #111188 for decorative elements or backgrounds with sufficient contrast provided by foreground elements. Employing contrast checking tools is essential to verify compliance with accessibility standards before deploying any design incorporating this color. A better approach would be to use a lighter shade of blue, which offers better contrast while maintaining the desired aesthetic.
