General Information about Blue Charcoal

The color #020818, known as Blue Charcoal, is a very dark shade of blue, almost appearing black to the untrained eye. It is composed of 0.8% red, 3.1% green, and 9.4% blue. In the RGB color space, it is very close to black, but the slight presence of blue gives it a distinct character. This color is often associated with sophistication, seriousness, and stability. In graphic design and web development, Blue Charcoal can be used to create a modern and professional look. However, due to its darkness, it's crucial to use it carefully, especially when it comes to accessibility considerations. It is essential to pair it with light-colored text to ensure readability and avoid straining the eyes of users.

The hex color #020818, also known as Blue Charcoal, presents significant accessibility challenges, primarily due to its very dark nature. Its contrast ratio against standard white backgrounds is extremely low, falling far short of WCAG (Web Content Accessibility Guidelines) recommendations for text and interactive elements. This makes it difficult for users with visual impairments, including those with low vision or color blindness, to perceive content accurately. To improve accessibility, it is crucial to pair this color with much lighter shades, ensuring a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Avoid using #020818 for critical interface elements without careful consideration of contrast. Thoughtful color combinations and adherence to accessibility standards are essential for inclusive design practices.
