In the RGB color model, it consists of 5/255 red (1.96%), 11/255 green (4.31%), and 21/255 blue (8.24%). This composition results in a color that is perceived as almost black, with a subtle blue undertone. Blue Charcoal is often associated with sophistication, mystery, and depth. Its hexadecimal representation, #050B15, is commonly used in web design and digital applications. The color's near-black nature makes it versatile for creating backgrounds, text, and other design elements where a muted and elegant aesthetic is desired. However, its low luminance necessitates careful consideration of contrast to ensure readability and accessibility, especially in user interfaces and textual content.

The hex color #050B15, a very dark shade, poses significant accessibility challenges, especially when used for text or interactive elements. Due to its low luminance, it requires extremely light foreground colors to meet WCAG (Web Content Accessibility Guidelines) standards for contrast ratio. A contrast ratio of at least 4.5:1 is necessary for normal text and 3:1 for large text. Using this color without careful consideration of contrast can result in content that is unreadable or difficult for users with visual impairments to perceive. Designers should use contrast checking tools to ensure sufficient contrast or consider lighter alternative colors to improve accessibility and inclusivity. It is crucial to test color combinations with users who have low vision to ensure readability and usability. Employing techniques like providing alternative text, using semantic HTML, and allowing users to customize color schemes can further enhance accessibility when working with very dark colors.
