The color #0C13A8, a deep ultramarine, presents some accessibility challenges, particularly when used as a text color. Due to its low lightness value, it requires careful consideration of contrast ratios. When used as text against a white background, it may not meet WCAG (Web Content Accessibility Guidelines) AA standards for normal text (4.5:1 contrast ratio). To ensure accessibility, it's crucial to pair it with a very light color for text or a very dark color for backgrounds. Using it for larger text sizes improves readability, but it's essential to test the color combination with accessibility tools to confirm compliance. Avoid using it for essential interactive elements without sufficient contrast. When using this color as a background, be mindful when using white or light-colored text to ensure it provides enough contrast for users to read and distinguish content effectively.
