General Information about #1B0900

The hexadecimal color code #1B0900 represents a very dark shade of brown, often referred to as Nero due to its near-black appearance. It is composed of 10.6% red, 3.5% green, and 0% blue. In the RGB color space, this translates to R:27, G:9, B:0. The HSL (hue, saturation, lightness) values are H:20, S:100%, L:5.3%. In the CMYK (cyan, magenta, yellow, key/black) color model, it consists of C:0%, M:67%, Y:100%, K:89%. Due to its extremely low lightness value, #1B0900 is generally perceived as a color of sophistication and power, but its low contrast makes it a challenging color for accessibility if not used carefully.

The color #1B0900, also known as Nero, presents significant accessibility challenges due to its extremely dark nature. Its low luminance results in very poor contrast against common background colors like white. This makes it difficult for individuals with visual impairments, including those with low vision or color blindness, to distinguish text or elements rendered in this color. To ensure accessibility, it is crucial to use #1B0900 sparingly and only in conjunction with very light colors that provide a high contrast ratio (ideally exceeding 4.5:1 for normal text and 3:1 for large text, as recommended by WCAG guidelines). Consider using accessibility evaluation tools to verify contrast ratios and ensure compliance with accessibility standards. Alternative color choices with better contrast should be explored whenever possible to create a more inclusive user experience.
