The color #0308BB, a deep and saturated blue, presents significant accessibility challenges, especially when used as text or interactive elements. Its low luminance results in poor contrast against light backgrounds, making it difficult for users with visual impairments, including those with low vision or color blindness, to distinguish content. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text. This dark blue is unlikely to meet these standards with typical white or light-colored backgrounds. Therefore, careful consideration must be given to ensure sufficient contrast. To enhance accessibility, consider pairing this color with very light shades or using it sparingly for decorative elements rather than essential content. Providing alternative text descriptions for images or icons using this color is also crucial.
