The color #2404AF, Ultramarine, presents significant accessibility challenges due to its low luminance. When used as text against a white background, or vice versa, it fails to meet the contrast ratios recommended by WCAG (Web Content Accessibility Guidelines) for both normal text (4.5:1) and large text (3:1). This means that users with visual impairments, including those with low vision or color blindness, may struggle to read content displayed in this color. To improve accessibility, consider using Ultramarine sparingly, particularly for decorative elements. When it is used for text or interactive elements, pair it with a very light or white color, or a very dark color to ensure sufficient contrast. Tools like contrast checkers can help determine if the combination meets accessibility standards. Providing alternative styling options for users to customize the color scheme can also enhance the user experience for those with specific visual needs.
