General Information about Blue Charcoal
The hex color code #000521, also known as Blue Charcoal, is a very dark shade of blue. In the RGB color model, it is composed of 0% red, 1.96% green, and 12.94% blue. This indicates a strong dominance of blue with minimal presence of red and green, resulting in its deep, muted appearance. In the CMYK color model, #000521 consists of 100% cyan, 62% magenta, 0% yellow, and 87% black. This composition reflects its use in printing, where a high percentage of black is needed to achieve the deep dark tone. Blue Charcoal evokes a sense of depth, mystery, and sophistication. Due to the limited brightness the color should only be used with care.
The hex color #000521, also known as Blue Charcoal, presents significant accessibility challenges due to its extremely low luminance. The very dark shade means text or interactive elements using this color as a background would require very light foreground colors to ensure sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Using #000521 as a background color necessitates careful selection of foreground colors to meet these standards. Insufficient contrast can lead to readability issues, especially for users with visual impairments. Therefore, when using #000521, prioritize high-contrast pairings and consider providing alternative color schemes to accommodate diverse user needs and preferences. Testing the color combination with accessibility tools is essential.

Applications
Web Design Accent
In web design, #000521 can be used sparingly for headers or accents where a deep, muted color is desired. However, it should be paired with very light text to ensure readability. It's suitable for creating a sophisticated and modern aesthetic. It can also be used for interactive elements that do not rely only on color to convey meaning. In charts and graphs, you may use the color as supporting or less important element. As a background color for larger displays the accessibility issues are less important, because of the physical size.
Interior Design Accent
In interior design, #000521 can be used as an accent wall color in a room with plenty of natural light. It pairs well with lighter, neutral colors to create a balanced and calming space. Consider using it in a bedroom or study to foster a sense of tranquility and focus. Alternatively, it can be used for furniture or decorative elements to add a touch of drama and sophistication.
