Blue Charcoal

#050B1A

General Information

The hex color code #050B1A, often referred to as Blue Charcoal, represents a very dark shade of blue found within the broader spectrum of blue colors. This particular hue is characterized by its deep, almost black appearance, with subtle blue undertones that distinguish it from pure black or gray. In the RGB color model, #050B1A is composed of 2% red, 4% green, and 10% blue, indicating a strong dominance of blue. Its primary use lies in designs where a sophisticated, understated, and somewhat mysterious aesthetic is desired. It works well in contexts where a dark and subtle color palette is appropriate, such as in backgrounds, accents, or text (when paired with a very light color for contrast). This color invokes feelings of sophistication and calmness due to its closeness to black but with an added hint of blue to avoid starkness.

The hex color #050B1A, also known as Blue Charcoal, presents significant accessibility challenges, primarily due to its low luminance. Its very dark nature results in poor contrast against light backgrounds, making text and other visual elements difficult to discern for users, especially those with visual impairments. 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 typically fails to meet these requirements when paired with common background colors like white or light gray. To improve accessibility, it's crucial to use this color sparingly, especially for text. When used, it should be paired with much lighter colors. Ensure sufficient contrast ratios using online contrast checkers to adhere to accessibility standards and provide a better user experience for everyone, including individuals with low vision or color blindness. Consider alternative color combinations that offer better contrast or employing techniques like adding borders or shadows to enhance visual clarity.
