General Information about #0B0A15

The hex color #0B0A15, also known as Cinder, is a very dark shade of gray, almost black. It belongs to the achromatic color group, meaning it lacks distinct hue and saturation. In the RGB color model, it is composed of 4.31% red, 3.92% green, and 8.24% blue. Its primary characteristic is its low luminance, which makes it appear very dark to the human eye. This color is often associated with feelings of sophistication, neutrality, and understated elegance. In web design and graphic design, it is typically used for backgrounds, text (when paired with a very light foreground color for sufficient contrast), or as an accent color to create a sense of depth or shadow. Its near-black appearance makes it a versatile choice for various design applications where a subtle, dark tone is desired.

The hex color #0B0A15, a very dark shade of gray, presents significant accessibility challenges, primarily due to its extremely low luminance. When used as a foreground color, it requires an exceptionally light background to ensure sufficient contrast for readability. According to WCAG guidelines, the contrast ratio between the text and background should be at least 4.5:1 for normal text and 3:1 for large text to meet AA compliance. Given the darkness of #0B0A15, achieving this contrast ratio is difficult, limiting its usability for body text or essential UI elements. Careful consideration must be given to color pairings. It is advisable to use a color contrast checker to verify compliance. For users with low vision or color blindness, the inherent lack of contrast can render content illegible. Furthermore, avoid using #0B0A15 for interactive elements like links or buttons unless accompanied by additional visual cues to differentiate them from surrounding text.
