General Information about Blue Charcoal (#050F19)

The hex color #050F19, often referred to as Blue Charcoal, is a very dark shade of blue, almost bordering on black. It evokes feelings of sophistication, mystery, and understated elegance. In the RGB color model, it's composed of 2% red, 6% green, and 10% blue, indicating a strong bias towards the blue end of the spectrum, although the overall intensity is quite low. Due to its low luminance, it is typically used as a background or accent color where a subtle, subdued effect is desired.

This color is popular in themes and designs that aim for a modern, minimalist aesthetic.

The color #050F19, also known as Blue Charcoal, presents significant accessibility challenges, especially concerning color contrast. Its very dark nature means that text or interactive elements rendered in this color require extremely light foreground colors to meet WCAG (Web Content Accessibility Guidelines) standards for readability. A contrast ratio of at least 4.5:1 is necessary for normal text and 3:1 for large text to ensure usability for individuals with visual impairments. When using Blue Charcoal, careful selection of foreground colors and thorough testing with accessibility evaluation tools are crucial. Designers should also consider providing alternative color schemes to accommodate users with specific visual needs, such as those with color blindness or low vision. Without these considerations, content using #050F19 may be inaccessible to a significant portion of users.
