The color #1A0B9A, a deep ultramarine, presents several accessibility considerations for web development. Its low luminance value (dark color) means it requires careful pairing with text and other foreground elements to ensure sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. When using #1A0B9A as a background, it is crucial to use light colors like white, light yellow, or light gray for the text. Tools like contrast checkers can help verify compliance. Also, avoid using this color as the sole indicator for interactive elements (links, buttons) as users with color vision deficiencies might not be able to distinguish them. Supplement color cues with text labels, icons, or other visual indicators to enhance accessibility.
