The hex color #03305b, a deep Prussian Blue, presents several accessibility considerations for web development. Its low luminance necessitates careful selection of foreground colors to ensure sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. White (#FFFFFF) or very light shades of yellow or orange could serve as suitable foreground colors to achieve this contrast. It's crucial to use contrast checking tools to verify compliance. Also, consider users with color vision deficiencies. Avoid using color as the sole means of conveying information. Supplement color cues with text labels, icons, or patterns. Proper implementation ensures content is accessible and inclusive to a wider audience, enhancing the overall user experience.
