#041019

General Information About Blue Charcoal

The hex color #041019, also known as Blue Charcoal, is a very dark shade of blue, almost bordering on black. It belongs to the blue color family and has very low saturation and luminance values. This color evokes feelings of depth, mystery, and sophistication. It is often used in design to create a sense of elegance and understated luxury. Due to its dark nature, it is important to consider contrast ratios when using this color in web design or other applications, particularly for text elements. This color is composed of 1.6% red, 6.3% green, and 9.8% blue. In the RGB color space, its values are R:4, G:16, B:25. The color is more frequently used in contexts where a near-black tone with a hint of blue is desired, providing a more nuanced and interesting alternative to pure black.

The hex color #041019, also known as Blue Charcoal, presents significant accessibility challenges, particularly in text-based contexts. Its extremely low luminance value of approximately 0.005 makes it difficult to achieve sufficient contrast against lighter backgrounds. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text to ensure readability for users with visual impairments. Using #041019 for text or important interface elements against a typical white or light-colored background would fall far short of these recommendations. To improve accessibility, consider using #041019 sparingly, if at all, for text. If it must be used, pair it with a very light color to reach an accessible contrast ratio. Otherwise, using it for decorative elements or as a background color for non-text elements, with careful selection of contrasting foreground elements, might be more suitable. Additionally, providing alternative color schemes or allowing users to customize colors can further enhance accessibility.
