General Information about Blue Charcoal

Blue Charcoal, represented by the hexadecimal color code #051118, is a very dark shade of blue-gray. In the RGB color model, it is composed of 2% red, 7% green, and 9% blue. Its darkness makes it appear almost black, making it useful for creating a sophisticated or understated aesthetic. The color is often associated with calmness, stability, and a sense of depth. In color psychology, dark blues can evoke feelings of trust and authority, while also promoting a sense of peace and relaxation. Due to its low luminance, Blue Charcoal is best used sparingly or combined with lighter colors to ensure readability and visual balance. It is a versatile color that can be incorporated into various design applications, from web development to interior design, providing a grounding and elegant touch.

The color #051118, also known as Blue Charcoal, presents significant accessibility challenges due to its very dark nature. With extremely low contrast against standard white text, readability is severely compromised for individuals with visual impairments. Web Content Accessibility Guidelines (WCAG) emphasize a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Blue Charcoal falls far short of these recommendations, making it difficult for users with low vision or color blindness to perceive content. To improve accessibility, consider using lighter text colors such as white or very light grays. Alternatively, employing Blue Charcoal sparingly for decorative elements rather than essential information can minimize accessibility issues. Tools like contrast checkers can help evaluate and adjust color combinations to meet WCAG standards, ensuring a more inclusive user experience. Careful consideration of color contrast is paramount in web design to provide equitable access to information for all users.
