Its low luminance results in poor contrast against lighter text or background elements. According to WCAG guidelines, sufficient contrast is crucial for readability, especially for users with visual impairments. To ensure accessibility, it's imperative to use #12151C with very light text (e.g., white or very pale shades of yellow or green) and to avoid using it for critical interactive elements unless accompanied by clear visual cues and labels. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. It is necessary to conduct thorough accessibility testing with various tools and user groups to validate compliance and make necessary adjustments.
