General Information about Blue Charcoal

Blue Charcoal, represented by the hex code #000523, is a very dark shade of blue. It belongs to the blue color family but possesses a muted and almost black-like appearance due to its extremely low luminance. This color is often associated with sophistication, elegance, and mystery. In color psychology, dark blues can represent trustworthiness, reliability, and authority. However, the darkness of Blue Charcoal can also evoke feelings of sadness or melancholy if used excessively. The color is composed of 0% red, 1.96% green, and 13.73% blue in the RGB color space. Due to its low brightness, it is not a common choice for primary colors in design but is more often used as an accent color or for creating a subtle, sophisticated background. Its hex code is composed of three pairs of hexadecimal numbers, each pair representing the intensity of the red, green and blue.

The hex color #000523, also known as Blue Charcoal, presents significant accessibility challenges, especially in text-based applications. Its extremely low luminance value of 0.002 means that it provides very poor contrast against standard white backgrounds. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Blue Charcoal falls far short of these requirements, making it difficult for users, particularly those with visual impairments, to read content displayed with this color. To improve accessibility, it is crucial to pair #000523 with much lighter colors that provide sufficient contrast. Alternatively, consider using #000523 sparingly for purely decorative elements where readability is not critical. Tools like contrast checkers can help evaluate and adjust color combinations to meet accessibility standards, ensuring a more inclusive user experience. Always prioritize the needs of all users when making color choices.
