General Information about Blue Charcoal

The hexadecimal color code #010A1A, often referred to as Blue Charcoal, is a very dark shade of blue that borders on black. It consists of 0.39% red, 3.92% green, and 10.2% blue. In the RGB color model, this color is created by mixing very small amounts of red and green with a slightly higher proportion of blue. The resulting hue is a deep, muted tone that evokes feelings of sophistication, mystery, and depth. Because of its low brightness and saturation, #010A1A is not typically used as a primary color, but rather as an accent or background element to create a sense of elegance and to allow other colors to stand out. It's essential to consider contrast ratios when using this color, particularly for text, to ensure readability and accessibility.

The color #010A1A, also known as Blue Charcoal, presents significant accessibility challenges due to its very dark nature. Its low luminance results in poor contrast against lighter backgrounds, making it difficult for individuals with visual impairments to discern text or graphical elements. According to WCAG guidelines, this color fails to meet the minimum contrast ratios for normal text, large text, and non-text contrast when paired with standard white (#FFFFFF). To ensure accessibility, it is crucial to use #010A1A sparingly, particularly for text or interactive elements. When it is used, it should be paired with extremely light colors like #FFFFFF or very pale shades of gray to provide adequate contrast. Assistive technologies may struggle to correctly interpret content rendered with insufficient contrast, leading to a diminished user experience. Alternatives should always be considered when accessibility is a priority.
