General Information about Blue Charcoal

The hex color #021219, also known as Blue Charcoal, is a very dark, muted shade of blue-green. In the RGB color model, it is composed of 0.78% red, 7.06% green, and 9.8% blue. This color is often associated with feelings of calmness, sophistication, and seriousness. Due to its low brightness, it tends to appear almost black, making it suitable for applications where subtlety is desired. The color's darkness means it reflects very little light, absorbing most wavelengths that hit its surface. Blue Charcoal is frequently employed in designs that require a sense of elegance, depth, or understated luxury, often pairing well with lighter, contrasting colors to create visual interest and ensure readability.

The hex color #021219, also known as Blue Charcoal, presents significant accessibility challenges due to its extremely low luminance. With such dark values, the contrast against standard light backgrounds is insufficient for users with visual impairments. Ensuring readability requires careful consideration of foreground text and interactive elements. A recommended approach involves pairing this color with significantly lighter shades, such as off-whites or pastels, to meet WCAG (Web Content Accessibility Guidelines) contrast ratio requirements. Furthermore, avoid using this color for essential visual cues without redundant indicators, as users with color deficiencies may struggle to differentiate it from similar dark tones. Thorough testing with accessibility evaluation tools and user feedback is crucial to validate the design choices and ensure an inclusive user experience.
