The color #00041B, also known as Blue Charcoal, is a very dark shade of blue. In the RGB color model, it is composed of 0% red, 1.57% green, and 10.59% blue. This composition results in a color that is perceived as deep, somber, and almost black. The low values across all color channels contribute to its dark nature. Blue Charcoal is often associated with qualities such as sophistication, mystery, and elegance. It's a color that evokes a sense of depth and can be used to create a feeling of calm or introspection.

This color finds applications in various fields, including web design, fashion, and interior design, where its deep hue can contribute to a sense of understated luxury or subtle drama.

The hex color #00041B, also known as Blue Charcoal, presents significant accessibility challenges, particularly in text-based applications. Its extremely low luminance results in very poor contrast against typical light backgrounds like white or light gray. This severely impacts readability for users, especially those with visual impairments or color vision deficiencies. 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 is unlikely to meet these standards against most backgrounds, necessitating careful consideration of color pairings. To improve accessibility, consider using lighter text colors, such as white or very light shades of gray or blue, or pairing it with significantly brighter background colors. Utilizing tools that check color contrast ratios is essential to ensure compliance with accessibility standards and provide an inclusive user experience. Proper implementation of ARIA attributes can also help provide additional context for screen readers and other assistive technologies.
