General Information about #131515

The hex color #131515, also referred to as 'Bunker', is a very dark, almost black shade. It belongs to the family of neutral colors and has very low saturation and luminance. In the RGB color model, #131515 is composed of 7.45% red, 8.24% green, and 8.24% blue. The color is mostly used as a background in web design to provide a contrast for light elements, and can also be used for printing to create a dark filling. Due to its darkness, care must be taken when using this color to ensure readability and accessibility, especially when it is combined with text or other important elements. Bunker evokes feelings of seriousness, strength, and sophistication.

The hex color #131515, also known as Bunker, presents significant accessibility challenges, particularly in text-based applications. Its low luminance value results in very poor contrast against standard white backgrounds, failing WCAG (Web Content Accessibility Guidelines) AA and AAA standards for normal text. This means individuals with low vision or color blindness may struggle to read content displayed in this color. To improve accessibility, it is crucial to pair #131515 with a light foreground color. White (#FFFFFF), light gray (#D3D3D3), or even a pale yellow (#FFFFE0) can provide sufficient contrast. Tools such as contrast checkers can precisely measure the contrast ratio. If #131515 is used for decorative elements, ensure critical information isn't conveyed solely through the color and that alternative visual cues are provided.
