General Information about Blue Charcoal

The hex color #010619, also known as Blue Charcoal, is a very dark shade of blue, almost appearing black to the naked eye. It belongs to the family of cool colors and evokes feelings of depth, mystery, and sophistication. In the RGB color model, it consists of 0.4% red, 2.4% green, and 9.8% blue. Its primary use is often in backgrounds or areas where a subtle, understated color is needed. Because of its low brightness, it's important to consider contrast when using it with text or other design elements. Blue Charcoal can lend a sense of elegance and formality to designs, and is often used in contexts where a calming or serious tone is desired.

The hex color #010619, also known as Blue Charcoal, presents significant accessibility challenges due to its extremely low luminance. With such a dark shade, it's crucial to use contrasting text and elements to ensure readability and usability. A light color, such as white or a very pale yellow, is highly recommended for text displayed against this background to meet WCAG (Web Content Accessibility Guidelines) standards for contrast ratios. Without adequate contrast, users with visual impairments, including those with low vision or color blindness, will struggle to perceive the content. For interactive elements, consider providing additional visual cues beyond color, such as underlines or icons, to enhance accessibility for all users. Furthermore, it is important to test the color combination with accessibility tools to verify compliance with accessibility standards.
