General Information about #131615

The hexadecimal color code #131615, often referred to as 'Bunker,' represents a very dark, muted shade of gray. In the RGB color model, it is composed of 7.45% red, 8.63% green, and 8.24% blue. Its primary characteristic is its near-black appearance, contributing to its use in designs where subtlety and a low profile are desired. This color falls within the gray color range, lacking strong saturation or hue. Given its low luminance, #131615 is commonly used to evoke feelings of sophistication, mystery, or a sense of calm. It's frequently employed in design contexts where minimizing distractions is crucial or where a dark backdrop is needed to make other elements visually pop. In terms of light reflectance, Bunker absorbs the vast majority of incoming light, making it a poor reflector and a strong absorber of light energy.

The hex color #131615, also known as Bunker, presents accessibility challenges due to its low luminance. Its dark nature results in very low contrast against standard light backgrounds (like white). This can make text or interactive elements using this color difficult to read or distinguish for users, especially those with visual impairments. To ensure accessibility, it's vital to use Bunker with high-contrast foreground colors, such as light yellows or near-white shades. Adhering to WCAG (Web Content Accessibility Guidelines) contrast ratios is crucial. For normal text (14pt or 18px and larger), a contrast ratio of at least 4.5:1 is recommended, while large-scale text (14pt bold or larger, or 18pt or 24px) requires a 3:1 ratio. When Bunker is used for UI components or graphics, a contrast ratio of 3:1 against adjacent colors is necessary. Careful consideration and testing with accessibility tools will ensure that content remains usable for all users.
