General Information about Blue Charcoal

The hex color #010D19, also recognized as Blue Charcoal, is a very dark shade of blue. It belongs to the blue color family, although it is so dark that it often appears nearly black. This color is composed of 0.4% red, 5.1% green, and 9.8% blue. In the RGB color model, these values translate to a subdued, deep tone. Blue Charcoal evokes feelings of sophistication, mystery, and tranquility. Its inherent darkness renders it a versatile choice for creating a sense of depth and elegance. It is frequently utilized in design contexts where a subtle, understated presence is desired. The color's low saturation also contributes to its versatility, enabling it to blend well with a broad spectrum of other colors and textures.

The hex color #010D19, also known as Blue Charcoal, presents accessibility challenges due to its low luminance. Its dark nature results in a very low contrast ratio against standard white text (or light backgrounds generally), making it difficult for users with visual impairments to read content. For web design, it's crucial to use this color sparingly and ensure sufficient contrast with foreground elements. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text (at least 18pt or 14pt bold) to comply with WCAG guidelines. Using tools to check color contrast is essential before implementing this color in a user interface. Consider pairing it with very light colors or using it for non-text elements, such as backgrounds or decorative accents, where legibility is less critical. To improve accessibility, use a lighter shade or combine it with high-contrast colors.
