The hex color #1B1B7C, also known as Deep Koamaru, presents several accessibility considerations for web developers. Its dark hue results in low luminance, which means it requires careful pairing with text and other foreground elements to ensure sufficient contrast. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text to meet AA compliance. For AAA compliance, these ratios increase to 7:1 and 4.5:1, respectively. When using #1B1B7C as a background, light colors such as white, light gray, or pale yellow would be suitable choices for text to meet these contrast requirements. Tools like WebAIM's contrast checker can be used to verify compliance. Also, avoid using this color for critical interactive elements without clear visual cues, as users with low vision may struggle to differentiate them. Screen reader users will not perceive the color, so ensure any conveyed information is also available through semantic HTML and ARIA attributes.
