General Information about Blue Charcoal

Blue Charcoal, represented by the hexadecimal color code #011415, is a very dark shade of blue. It leans heavily towards black, with subtle undertones of blue and green. This color is often associated with sophistication, calmness, and depth. In color theory, it's considered a cool color, evoking feelings of tranquility and stability. Due to its low luminance, Blue Charcoal is best used as an accent color or paired with lighter, contrasting colors to ensure readability and visual clarity. It is commonly used in designs where a subtle, understated elegance is desired. The RGB values are R:1, G:20, B:21, which confirms the dominance of black with slight tints of blue and green. Its very low saturation makes it appear almost monochromatic.

The color #011415, also known as Blue Charcoal, presents significant accessibility challenges, particularly for users with visual impairments. Its extremely low luminance value (very dark) results in poor contrast against most background colors, especially white. According to WCAG guidelines, sufficient contrast is crucial for readability and usability. Using #011415 for text or interactive elements against a light background would likely fail WCAG AA and AAA standards. To improve accessibility, web developers should avoid using this color for text or interactive elements unless paired with a very light color to achieve a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Consider using color contrast analyzers to verify compliance. Furthermore, avoid using color as the sole means of conveying information; supplement it with text labels or other visual cues.
