The hex color #05019a, also known as Ultramarine, presents significant accessibility challenges, particularly in web design. Its very dark hue results in a low contrast ratio against standard light backgrounds, making text or interactive elements difficult to read for users with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Ultramarine typically fails to meet these standards when paired with white or light-colored backgrounds. To improve accessibility, it is crucial to use Ultramarine sparingly, especially for text. When it is necessary to use the color, it should always be paired with a very light color to ensure sufficient contrast. It's important to test the color combination with accessibility tools to verify compliance with WCAG standards and ensure readability for all users.
