The color #040694, a deep ultramarine, presents significant accessibility challenges. Its extremely low luminance value of approximately 0.004 necessitates careful consideration for users with visual impairments. According to WCAG guidelines, this color fails against both AA and AAA standards for normal text at any size when paired with black (#000000). For sufficient contrast, it requires a light color, such as white (#FFFFFF) or a very light gray. However, even with white text, it might not meet the enhanced AAA contrast ratio of 7:1, especially for smaller text sizes. Therefore, it is essential to evaluate the contrast ratio using a contrast checker and to provide alternative styling options for users who need them. Consider increasing the text size, using a bold font weight, or providing a high-contrast theme option to improve readability. Also avoid using this color for important information as it will not be easily readable by many users.
