Blue Charcoal
General Information about #021018
The hexadecimal color code #021018 represents a very dark shade of blue, often referred to as Blue Charcoal. It is composed of 0.78% red, 6.27% green, and 9.41% blue. In the RGB color model, this translates to 2 red, 16 green, and 24 blue. This color has a very low saturation and brightness, making it appear almost black. Due to its muted nature, it evokes feelings of sophistication, mystery, and calmness. It is often used in designs to create a sense of depth or to provide a subtle background. Its low luminance makes it challenging to use for text or interactive elements without careful consideration of contrast ratios. The color is more prominent in digital designs and printing.
The hex color #021018, also known as Blue Charcoal, presents significant accessibility challenges due to its extremely low luminance. Its contrast ratio against standard white (#FFFFFF) is very poor, making text and other visual elements rendered in this color difficult to perceive, especially for users with visual impairments or color vision deficiencies. To ensure inclusivity, it is crucial to pair this color with very light shades or white for foreground elements like text. Tools that measure contrast ratios, as defined by WCAG guidelines, should be employed to verify compliance. Ideally, a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text should be achieved. Using this color sparingly and thoughtfully in design, with careful consideration of its impact on users with disabilities, is highly recommended. Avoid using #021018 for essential interactive elements where clear visibility is paramount.

However, always ensure sufficient contrast with foreground elements, especially text and interactive components. Pair it with light text or graphical elements to ensure readability and accessibility.

Consider using it for smaller elements like cushions, throws, or artwork to add a touch of drama without overwhelming the space.

In fashion, #021018 can be used for creating elegant and minimalist looks. Consider using it for formal wear or outerwear. When incorporated into clothing, pair it with lighter colors or metallic accents to create visual interest. The color exudes sophistication and can be used to create a sense of understated luxury. Use it as a foundation color for accessories and build a harmonious palette that combines it with neutrals or contrasting colors for balance and flair.
