General Information about #131115

The hex color #131115, often referred to as 'Bunker,' is a very dark, desaturated shade of gray, almost black. It belongs to the family of neutral colors and is characterized by its low luminance and chroma values. In the RGB color model, #131115 consists of 7.45% red, 6.67% green, and 8.24% blue. In the CMYK color model, it is composed of approximately 10% cyan, 19% magenta, 0% yellow, and 92% black. This color is commonly used to evoke feelings of sophistication, mystery, or seriousness. Its near-black appearance makes it suitable for creating a sense of depth or shadow in designs. However, its low luminance also presents challenges in terms of accessibility, particularly concerning contrast ratios against light backgrounds. Therefore, its use should be carefully considered in contexts where readability is crucial.

The hex color #131115, often referred to as 'Bunker,' presents significant accessibility challenges, particularly in web design. Its extremely low luminance value results in very poor contrast against typical light backgrounds, such as white (#FFFFFF). According to WCAG (Web Content Accessibility Guidelines) standards, sufficient contrast is crucial for readability and usability, especially for users with visual impairments. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. #131115 will likely fail these contrast tests against most standard background colors. Therefore, using this color for text or important UI elements on a light background is strongly discouraged. If this color is essential for branding, consider pairing it with very light colors to ensure sufficient contrast and conduct thorough accessibility testing with assistive technologies to confirm usability for all users. Alternatively, use it sparingly for decorative elements where contrast is less critical.
