Blue Charcoal

General Information about Blue Charcoal

The hexadecimal color code #05091A, often referred to as Blue Charcoal, is a deep, dark shade of blue with a subtle hint of gray. It belongs to the family of blue colors but possesses a significantly muted and desaturated quality, contributing to its charcoal-like appearance. The color is composed of 2% red, 4% green, and 10% blue in the RGB color model. In the CMYK color model, used in printing, it consists of 95% cyan, 91% magenta, 0% yellow, and 90% black. Blue Charcoal's low luminance value makes it appear very dark to the human eye, lending it a sophisticated and calming feel. This color is often associated with depth, mystery, and elegance and finds applications in various fields, from web design to fashion.

The hex color #05091A, also known as Blue Charcoal, presents significant accessibility challenges due to its extremely low luminance. Its dark nature means it provides very little contrast against most background colors, particularly white (#FFFFFF) or other light shades. This lack of contrast makes it difficult for users with visual impairments, such as those with low vision or color blindness, to distinguish text or interactive elements rendered in this color. Web Content Accessibility Guidelines (WCAG) emphasize a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text to ensure readability. Blue Charcoal falls far short of these recommendations, necessitating careful consideration and the use of high-contrast alternatives to maintain an inclusive and accessible user experience. When using this color, ensure that all text is accompanied by a very light background, and that non-text elements have sufficient contrast against adjacent colors to be easily discernible.

However, it should be used sparingly and with careful consideration for accessibility. The dark hue of Blue Charcoal makes it unsuitable for body text or large blocks of content, as it can strain the eyes and reduce readability. When using this color, it is crucial to prioritize contrast by pairing it with light or vibrant colors for text and interactive elements, ensuring a positive user experience.
