The hex color #040897, a deep ultramarine, presents considerable accessibility challenges, especially in web design. Its very low luminance makes it difficult to read text against a white or light background. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. This color falls far short of these recommendations when paired with typical background colors, potentially causing visual strain for users, particularly those with low vision or color blindness. To improve accessibility, consider using #040897 sparingly and always ensure sufficient contrast by pairing it with a very light color, such as white (#FFFFFF) or a pale yellow. Tools are available to measure color contrast ratios and ensure compliance with accessibility standards. Employing these tools is crucial when using such a dark hue to guarantee a positive user experience for everyone.
