Blue Charcoal
General Information
The hexadecimal color code #020518 represents a very dark shade of blue, often referred to as Blue Charcoal. In the RGB (Red, Green, Blue) color model, it is composed of 1.18% red, 1.96% green, and 9.41% blue. This color is primarily used in contexts where a deep, muted tone is desired, such as backgrounds in digital design or in situations where a subtle, understated visual effect is needed. Due to its high blue component and low overall luminance, it is generally perceived as a cool and calming color. In the CMYK (Cyan, Magenta, Yellow, Key/Black) color model, #020518 is composed of 87% cyan, 79% magenta, 0% yellow, and 91% black.
The hex color #020518, also known as Blue Charcoal, presents significant accessibility challenges, particularly in text-based applications. Due to its extremely low luminance, using this color as a background for lighter text or vice versa will result in very poor contrast. This violates WCAG (Web Content Accessibility Guidelines) standards, specifically the contrast ratio requirements for readability. To ensure accessibility, avoid pairing #020518 with other dark colors. If used as a background, ensure text is a very light color (e.g., white or very pale yellow). Tools like contrast checkers are essential to validate that sufficient contrast is achieved (a minimum of 4.5:1 for normal text and 3:1 for large text). Consideration should also be given to users with low vision or color blindness, who may experience difficulties distinguishing elements with such low contrast. Careful design choices and adherence to accessibility guidelines are crucial when implementing this color.

Applications
Web Design
In web design, #020518 can create a sophisticated and mysterious aesthetic when used sparingly. It's often applied in website headers or footers to give depth to the layout. However, it should be used with caution for larger backgrounds because readability is affected. Combine it with brighter accent colors such as vibrant blues or teals to achieve visual balance and ensure that key interactive elements are easily noticed. For example, a website dedicated to cybersecurity might choose #020518 as one of its primary colors to convey a sense of seriousness and sophistication, but then incorporate bright neon shades for important notification messages.
Interior Design
In interior design, #020518 evokes a sense of modern minimalism and elegance. It's ideal for creating accent walls in living rooms or bedrooms, or in smaller spaces like home offices or entertainment rooms. The color pairs well with metallic accents such as silver or brushed nickel, and natural materials like dark wood or leather. Use it in rooms where you seek a sophisticated and cozy atmosphere. For example, a study with walls painted in #020518, complemented by a light colored oak desk and a leather chair could make a great combination.
Fashion
In fashion, designers can use #020518 for outerwear, dresses, or evening wear to convey sophistication. This is a good choice for those who want to avoid classic black. Given its dark nature, it is a flattering color for all skin tones. Combining this color with gold or silver accessories enhances its sophisticated nature and elevates any outfit. When used in makeup, such as for eyeliner or eyeshadow, it offers a bold, modern look. The shade can be softened by blending it with lighter neutrals to create a smoky effect.
