General Information about #09131B

The hex color #09131B, often referred to as 'Bunker,' is a very dark shade of cyan-blue. It belongs to the dark end of the color spectrum, possessing minimal luminance and saturation. In the RGB color model, it is composed of 3.53% red, 7.45% green, and 10.59% blue. This color is generally perceived as subdued, serious, and sophisticated. Due to its limited brightness, it is often used in contexts where a subtle, understated visual impact is desired. However, caution is advised when using this color in applications that require readability or accessibility, as its low contrast against lighter backgrounds can pose challenges for users, especially those with visual impairments. Its dark characteristics makes the color a good choice for background, while light colors can be used for foreground to create good contrast.

The hex color #09131B, also known as Bunker, presents significant accessibility challenges due to its very low luminance. Its dark nature results in extremely poor contrast against standard light backgrounds, making text and other visual elements rendered in this color difficult, if not impossible, for many users to perceive. This is especially problematic for individuals with visual impairments or color vision deficiencies. Web developers should avoid using #09131B for text or important interface elements unless paired with a very light color to achieve an acceptable contrast ratio, ideally exceeding the WCAG AA standards of 4.5:1 for normal text and 3:1 for large text. Thorough testing with accessibility evaluation tools and real users is crucial to ensure usability.
