General Information about Blue Charcoal
The hex color code #040717, also known as Blue Charcoal, is a very dark shade of blue, almost black. It is composed of 1.57% red, 2.75% green, and 9.02% blue. In the RGB color model, this translates to the values R:4, G:7, B:23. The CMYK representation of #040717 is C:83, M:70, Y:0, K:91. This color is typically associated with feelings of calmness, depth, and sophistication. Due to its dark nature, it is often used in backgrounds or as an accent color when a sense of elegance and subtlety is desired. The color is rarely used in a place where readability is important, due to the fact that you would need a very light color to be able to contrast the dark color and still be read.
The hex color #040717, also known as Blue Charcoal, presents significant accessibility challenges, especially in text-based contexts. Its extremely low luminance value means that it provides very little contrast against most background colors, particularly white or light shades. According to WCAG guidelines, sufficient contrast is crucial for readability and usability, especially for users with visual impairments. To ensure accessibility, this color should be paired with a very light color for text or interactive elements. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Using tools to check contrast ratios is highly advisable when implementing this color in web design. Employing techniques like text shadows or borders can sometimes help improve legibility but should not be the primary solution. Thoughtful consideration of color combinations is paramount to avoid creating barriers for users.

Applications
Website Background
This color can serve as a sophisticated background in website designs aiming for a dark and modern feel. Its deep, muted tone provides a sense of depth without being overly distracting. However, the designer should be mindful to use contrasting text colors (like white or light yellows) to make the content easily readable. It's particularly effective for portfolio websites, tech blogs, or landing pages where a refined and understated aesthetic is desired. To enhance the visual appeal, you could subtly use shades of gray or blue as complementary colors in other parts of the website.
Mobile App UI
In mobile app development, Blue Charcoal can be used for the primary background color of an application with a focus on media consumption or content creation. A dark interface can reduce eye strain during prolonged use. This color choice can be complemented with light-colored icons and text to achieve a modern and accessible design. This would also be great for e-readers and other reading apps.
Fashion Design
In fashion, this color is suitable for elegant and formal wear, often used in suits, dresses, and accessories. It conveys sophistication and class. Because it is so dark, consider using this color in the colder months. For women, consider the color for a sleek business look.
