General Information about Blue Charcoal

The hexadecimal color #010B1A, also known as Blue Charcoal, is a very dark shade that lies within the blue color spectrum. It is composed of 0.39% red, 4.31% green, and 10.2% blue. In the RGB color space, this equates to (1, 11, 26). Due to its high concentration of blue compared to red and green, the color evokes a sense of depth, mystery, and sophistication. Blue Charcoal is often associated with professionalism, formality, and a touch of somberness. In practical applications, such as web design or graphic design, it is crucial to consider the low luminance value of this color, which is approximately 0.73 cd/m². This requires careful selection of contrasting colors, particularly for text and interactive elements, to ensure readability and accessibility for all users.

The color #010B1A, also known as Blue Charcoal, presents significant accessibility challenges due to its extremely low luminance. With such a dark shade, it becomes imperative to use very light text colors, such as white or very pale yellows, to ensure sufficient contrast for readability. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Blue Charcoal is highly unlikely to meet these standards with moderately dark text. Designers must carefully evaluate the contrast ratio using accessibility tools to confirm compliance. Overlooking this can result in content that is difficult or impossible for users with visual impairments to perceive, leading to a poor user experience and potential legal repercussions. Consideration should also be given to users accessing the content on various devices and under different lighting conditions, as this can further impact readability. Proper testing and adjustments are crucial.
