The hex color #151088, a deep shade of ultramarine, presents significant accessibility challenges, especially in web design. Its low luminance value requires careful consideration of color contrast ratios to ensure readability and usability for individuals with visual impairments. According to WCAG guidelines, sufficient contrast is crucial for text and interactive elements. When using #151088 as a background color, it's imperative to pair it with a light-colored text (e.g., white or a very light gray) to achieve a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Tools like WebAIM's Contrast Checker can help verify compliance. Avoid using this color for elements where precise color differentiation is essential, and always provide alternative cues, such as icons or text labels, alongside color-coded information to accommodate users with color vision deficiencies.
