General Information about Blue Charcoal

The hex color #050619, also known as Blue Charcoal, is a very dark shade of blue. In the RGB color model, it is composed of 2.0% red, 2.4% green, and 9.8% blue. This color is best described as a deep, muted blue with near-black characteristics. It lacks vibrancy, making it suitable for applications where subtlety and sophistication are desired. Blue Charcoal can evoke feelings of calmness, stability, and mystery. Due to its darkness, it is often used as a background color to provide high contrast for lighter text and design elements. In the HSL color space, #050619 has a hue of 233 degrees, a saturation of 66%, and a lightness of 6%. Colors with such low lightness values tend to be very challenging to work with when considering accessibility guidelines. Blue Charcoal's dark, understated nature makes it a favorite for creating a serious and contemplative atmosphere.

The hex color #050619, also known as Blue Charcoal, presents significant accessibility challenges, especially in text-based applications. Its extremely low luminance value of approximately 0.003 makes it difficult to achieve sufficient contrast against lighter backgrounds. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text to ensure readability for individuals with visual impairments. When using #050619 as a background or text color, it's crucial to pair it with very light colors, such as white or very pale yellow, to meet these contrast requirements. Tools like contrast checkers can help determine if the chosen color combination meets accessibility standards. Avoid pairing it with mid-tone or dark colors, as this will invariably fail accessibility checks. Consider alternative, lighter shades if stringent accessibility compliance is a priority.
