Its low luminance makes it a challenging color to use for text or interactive elements without careful consideration of contrast ratios.

The hex color #010B13, also known as Blue Charcoal, presents significant accessibility challenges due to its very low luminance. With such a dark shade, it's crucial to ensure sufficient contrast when used with text or interactive elements. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. #010B13 will likely fail these contrast tests against many common background colors, including white. To improve accessibility, consider using lighter text colors like white, light gray, or even light blue, and always test the contrast ratio with tools like WebAIM's Contrast Checker. Avoid using this color for essential UI elements without ensuring adequate contrast.
