General Information about #021319

The hex color #021319, often referred to as Blue Charcoal, is a very dark shade of blue with minimal saturation and lightness. It belongs to the family of cool colors and evokes feelings of calm, sophistication, and mystery. In the RGB color model, #021319 consists of 0.78% red, 7.45% green, and 9.8% blue. The color is very close to black, making it suitable for use as a background color or as an accent color when paired with brighter, contrasting hues. Because of its low luminosity, it is important to consider accessibility guidelines when using this color in text or user interface elements to ensure readability for all users. The color is not very common, but sometimes it can be found in marketing design, where you want to create a elegant and modern look.

The hex color #021319, also known as Blue Charcoal, presents significant accessibility challenges due to its extremely low luminance. The contrast ratio against a standard white background (or even lighter shades of gray) is drastically below the WCAG (Web Content Accessibility Guidelines) recommended ratios for both normal text (4.5:1) and large text (3:1). This means that text rendered in this color on a light background would be very difficult for users with visual impairments, including those with low vision or color blindness, to read. Therefore, it is crucial to avoid using #021319 for text or important graphical elements without ensuring a sufficiently contrasting background color. Lighter shades of gray, yellows, or greens are potential contrasting colors. Always test the contrast ratio using accessibility tools to verify compliance with WCAG standards and ensure a positive user experience for all users. Using this color requires careful planning and consideration of its impact on readability and usability.
