The hexadecimal color code #020817, also known as Blue Charcoal, represents a very dark shade of blue. In the RGB color model, it is composed of 0.78% red, 3.14% green, and 9.02% blue. This color is frequently described as a muted and deep tone, evoking feelings of calmness and sophistication. It's commonly used in design contexts where a subtle, non-intrusive background is desired. The low saturation and brightness values contribute to its understated appearance.

The color is mostly used for backgrounds and less for fonts.
The color #020817, also known as Blue Charcoal, presents significant accessibility challenges, primarily due to its very low luminance. With such a dark hue, ensuring sufficient contrast against text or other interactive elements is paramount. The Web Content Accessibility Guidelines (WCAG) require specific contrast ratios to ensure readability and usability for individuals with visual impairments. To meet these guidelines, it's crucial to pair this color with very light text or interface elements. For example, using white or very pale shades of yellow or green can create the necessary contrast. Furthermore, when using this color as a background, avoid placing critical information or interactive elements on it without careful consideration of contrast. Employing tools that measure contrast ratios can help designers and developers verify compliance with accessibility standards, ultimately creating a more inclusive and user-friendly experience.
