The color #0109C9, a deep, dark blue, presents several accessibility considerations for web developers. Its low luminance value means it offers poor contrast when paired with other dark colors, potentially making text or interface elements difficult to read for users with visual impairments. According to WCAG guidelines, sufficient contrast ratios are crucial for readability. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text.

Supplement color cues with text labels or icons to ensure universal usability.
