General Information about Blue Charcoal

The hex color #021019, often referred to as Blue Charcoal, is a very dark shade of blue with subtle charcoal undertones. It belongs to the family of dark blues, almost appearing black in some lighting conditions. In the RGB color model, #021019 is composed of 0.8% red, 6.3% green, and 9.8% blue. This composition makes it a very desaturated color. The color's hexadecimal representation provides a standardized way to define it in digital contexts, particularly in web design and graphic design. Due to its dark nature, it can evoke feelings of sophistication, mystery, and depth. The color is not very common as it requires special consideration in designs to guarantee readability and contrast.

The hex color #021019, also known as Blue Charcoal, presents significant accessibility challenges due to its extremely low luminance. Its contrast ratio against a standard white background is very poor, making it difficult for individuals with visual impairments, including those with low vision or color blindness, to distinguish text or elements using this color. To ensure inclusivity, it is crucial to avoid using #021019 for text or important graphical elements unless paired with a very light color that provides sufficient contrast. Web Content Accessibility Guidelines (WCAG) recommend specific contrast ratios for different text sizes to ensure readability. When using #021019, developers should rigorously test the color combination with accessibility tools to verify compliance with WCAG standards. Consider alternative, lighter colors or using a darker background to improve readability and overall accessibility for all users.
