General Information about Blue Charcoal

The hex color code #000B22, also known as Blue Charcoal, represents a very dark shade of blue. In the RGB color model, it consists of 0 red, 11 green, and 34 blue. This translates to a very low red and green component with a slightly higher, but still minimal, blue component. In the HSL color space, #000B22 has a hue of 217 degrees, a saturation of 100%, and a lightness of 7%. This indicates a deep, saturated blue with very low luminance. Blue Charcoal is often associated with feelings of calmness, depth, and mystery. Due to its darkness, it is typically used as a background color or an accent color rather than for primary text. Its subtle nature makes it a good choice for creating a sophisticated and understated look.

The hex color #000b22, also known as Blue Charcoal, presents significant accessibility challenges, particularly in text-based contexts. Its extremely low luminance value results in very poor contrast against lighter backgrounds, potentially rendering text unreadable for users 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. This color is highly unlikely to meet these standards when paired with most common background colors. Designers should avoid using #000b22 for text or interactive elements unless paired with a very light color that provides adequate contrast. Tools like contrast checkers can assist in evaluating the color combination's accessibility. When using this color for decorative purposes, such as backgrounds or non-essential graphics, the accessibility concerns are reduced but should still be considered in relation to surrounding elements.
