The color #1809DD, a dark blue, presents significant accessibility challenges, particularly for users with visual impairments. Its low luminance value (approximately 4.3) results in poor contrast against typical light-colored backgrounds like white (#FFFFFF). According to WCAG guidelines, a contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text to ensure readability. This dark blue fails to meet these standards, making text difficult to discern for users with low vision, color blindness, or cataracts. To improve accessibility, consider using lighter shades of blue or pairing it with a high-contrast background color like white or yellow. Ensuring sufficient contrast is crucial for providing an inclusive web experience.
