Blue Charcoal
General Information
The hex color #040A1E, also known as Blue Charcoal, is a very dark shade of blue with subtle hints of gray. In the RGB color model, it is composed of 1.57% red, 3.92% green, and 11.76% blue. Its primary characteristic is its extremely low luminance, making it appear almost black. In terms of color theory, Blue Charcoal evokes feelings of sophistication, mystery, and calmness. It is often used in design to create a sense of depth and elegance. Due to its dark nature, it is crucial to consider accessibility when using this color, particularly in digital applications. Careful consideration must be given to contrast ratios to ensure readability and usability, especially for individuals with visual impairments.
The hex color #040A1E, also known as Blue Charcoal, presents significant accessibility challenges, particularly in text-based applications. Its extremely low luminance value of approximately 0.004 makes it difficult to distinguish from black, resulting in poor contrast against most background colors. According to WCAG (Web Content Accessibility Guidelines), a contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text against its background to meet AA compliance. Blue Charcoal falls far short of these recommendations. To improve accessibility, it's crucial to pair this color with much lighter hues. Consider using it sparingly for purely decorative elements or in situations where readability is not a primary concern. Implementing a contrast checker is highly advised during the design phase to guarantee accessible color pairings. Always test your color schemes with users, including those with visual impairments, to ensure usability.

Web Design Backgrounds
In web design, Blue Charcoal can be used sparingly for background elements or decorative accents to create a sophisticated and dark aesthetic. However, due to its low contrast, it should not be used for text or interactive elements without careful consideration of accessibility. It can be paired with lighter shades of blue or complementary colors like pale yellows or oranges to create a visually appealing contrast. Designers can use it to achieve a sense of depth and calmness when applied judiciously. Avoid using it in large blocks of text or interactive elements that require high readability.
Interior Design Accent
In interior design, Blue Charcoal can be used to create a moody and sophisticated atmosphere. It works well in bedrooms or living rooms where a sense of calmness and relaxation is desired. When using it on walls, balance it with lighter furniture and accessories to prevent the space from feeling too dark or small. This color pairs beautifully with metallic accents like gold or silver, and it also complements natural materials like wood and stone. Consider using it in smaller areas like an accent wall or a reading nook.
Fashion Apparel
In fashion, Blue Charcoal can be used as a sophisticated alternative to black, offering a softer, more nuanced look. It is a versatile color that can be incorporated into both casual and formal wear. This color works well for outerwear, such as coats and jackets, as well as for evening wear and accessories. It can be paired with a variety of colors, including neutrals like gray and beige, as well as bolder colors like burgundy and emerald green. Avoid using it for entire outfits, and rather utilize in conjunction with other colors.
