The color #030994, a deep ultramarine, presents significant accessibility challenges, especially in text applications. Its low luminance value of 0.011 makes it difficult to read against darker backgrounds, and even against white, the contrast ratio falls far below WCAG recommendations. A contrast ratio of at least 4.5:1 is needed for small text and 3:1 for large text. To improve accessibility, it is recommended to use this color sparingly for text and only with very light backgrounds, ensuring a contrast ratio that meets accessibility standards. When using this color for interactive elements, it's crucial to provide clear visual cues beyond color alone. Consider adding borders, icons, or text labels to enhance usability for users with visual impairments. Furthermore, always test color combinations with accessibility tools to ensure compliance.
