It resides in the dark end of the color spectrum and exhibits minimal saturation. The RGB (Red, Green, Blue) values are R:5, G:12, B:21, indicating that it contains very little red, a bit more green, and a moderate amount of blue. Its primary characteristic is its low luminance, making it suitable for applications where a subtle and understated color is desired.

Its use is prevalent in designs aiming for a sleek, modern, or professional aesthetic.

The hex color #050c15, also known as Blue Charcoal, presents significant accessibility challenges, particularly in web design. Its very low luminance of approximately 0.007 means that text or interactive elements using this color as a background are likely to fail WCAG (Web Content Accessibility Guidelines) contrast ratio requirements. Specifically, it is crucial to use foreground text or elements with a significantly lighter color to ensure readability for users with visual impairments. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Therefore, careful consideration and testing are essential when implementing this color to maintain an inclusive user experience. For improved accessibility, pairing #050c15 with lighter shades of gray or colors from the yellow spectrum can enhance visibility and reduce eye strain.
