The color #051498, a deep ultramarine, presents significant accessibility challenges. Its very low luminance value of 0.007 makes it difficult to read text against a white or light background. According to WCAG guidelines, the contrast ratio should be at least 4.5:1 for normal text and 3:1 for large text. This color will likely fail these criteria against most background colors, necessitating careful consideration. To improve accessibility, pair #051498 with very light or white text and consider increasing the font size and weight. Employing a text shadow or glow can also enhance readability. Always test color combinations with accessibility evaluation tools to ensure compliance and optimal user experience, especially for users with visual impairments. Avoid using this color for crucial interactive elements without sufficient contrast.
