The color #030398, a deep ultramarine, presents significant accessibility challenges. Its extremely low luminance of approximately 0.003 makes it very difficult to read against a standard white background. According to WCAG guidelines, it fails all contrast ratio tests for normal text, large text, and graphical objects against white. To ensure accessibility, it's crucial to avoid using #030398 for text or important graphical elements without careful consideration. When using this color, always pair it with a very light color like white (#FFFFFF) or a very pale yellow to ensure sufficient contrast. For enhanced readability, a text size of at least 18 points is recommended when paired with a light color. Implementing a dark background or considering a slightly lighter shade of blue could drastically improve contrast and make the content more accessible to users with visual impairments, including those with low vision or color blindness. Proper color choices significantly impact usability.
