The hex color #0A0F21, also known as Ebony, presents significant accessibility challenges. Its extremely low luminance value makes it unsuitable for text or interactive elements without careful consideration of contrast ratios. According to WCAG guidelines, sufficient contrast is crucial for users with visual impairments. To ensure accessibility, text using #0A0F21 as a background must be paired with very light text, or vice versa. A contrast ratio of at least 4.5:1 is recommended for normal-sized text and 3:1 for large text. Tools like contrast checkers can help verify compliance. Avoid using this color for essential UI components unless high contrast is guaranteed. Otherwise, users may struggle to perceive content and interactions effectively, leading to a poor user experience. The color should also not be the sole indicator of focus or state, and alternative cues should be provided.
