General Information About Blue Charcoal
The color #030B18, also known as Blue Charcoal, is a very dark, muted shade of blue, categorized within the broader family of blue hues. It is composed of 1.18% red, 4.31% green, and 9.41% blue. In the RGB color space, it translates to 3 red, 11 green, and 24 blue. This composition places it towards the lower end of the color spectrum in terms of brightness and saturation. Blue Charcoal evokes a sense of depth, calmness, and sophistication, making it a popular choice in designs aiming for a subtle and refined aesthetic. Its dark nature often requires careful consideration of contrast when used in conjunction with text or other visual elements to ensure readability and accessibility.
The hex color #030B18, also known as Blue Charcoal, presents significant accessibility challenges, particularly in text-based applications. Its extremely low luminance results in very poor contrast against virtually any lighter background. This poses readability issues for users with low vision or color blindness. According to WCAG guidelines, sufficient contrast ratios are essential for ensuring content is perceivable. For normal text (14 points), a contrast ratio of at least 4.5:1 is needed, and for large text (18 points), a ratio of 3:1 is necessary. #030B18 falls far short of these requirements, making it unsuitable for primary text or important UI elements without careful consideration of foreground color choices. To mitigate these accessibility issues, consider using much lighter text colors, such as whites or very pale yellows, and ensure thorough testing with accessibility evaluation tools.

Website Backgrounds
Blue Charcoal is a sophisticated color choice for website backgrounds, especially when aiming for a dark mode aesthetic. Its deep, muted tone provides a calming backdrop that reduces eye strain. However, careful consideration must be given to the foreground elements. Use contrasting colors like white or light pastel shades for text and icons to ensure readability and accessibility. The color can be complemented with brighter accent colors to highlight key interactive elements, such as buttons or calls to action, guiding the user's attention effectively.
Fashion Design
In the realm of fashion, Blue Charcoal offers a versatile and understated elegance. It serves as an excellent base color for creating sophisticated and timeless outfits. This color can be used in outerwear, such as coats and jackets, or in foundational pieces like trousers or skirts. It pairs well with a variety of colors, from neutral tones like beige and gray to bolder hues like burgundy or emerald green. The key is to strike a balance between the subdued nature of the color and the vibrancy of the accent colors to create a stylish and harmonious look.
Interior Design
Blue Charcoal can add depth and sophistication to interior spaces. It works well in accent walls, furniture upholstery, or even as a subtle color for cabinetry. This color creates a cozy and inviting atmosphere, particularly in living rooms or bedrooms. To prevent the space from feeling too dark or monotonous, incorporate lighter colors and textures through rugs, artwork, and accessories. Metallic accents, such as gold or silver, can also enhance the richness and visual appeal of Blue Charcoal in interior design.
