Given its dark nature, it is crucial to use it judiciously and pair it with lighter colors to maintain visual balance and ensure readability, especially in contexts like web design or print media.

The hex color #180b04, also known as Asphalt, presents significant accessibility challenges, especially for users with visual impairments. Its very low luminance value of approximately 0.008 makes it a very dark color, offering extremely poor contrast against light backgrounds. According to WCAG (Web Content Accessibility Guidelines), sufficient contrast is crucial for readability and usability. Text or interactive elements using #180b04 on a white or light-colored background will likely fail WCAG's contrast ratio requirements, potentially causing difficulties for users with low vision or color blindness. To improve accessibility, consider using lighter text colors such as white or very light grays on this dark background. Alternatively, avoid using this color for text altogether and reserve it for purely decorative elements where its impact on usability is minimal. Implementing these adjustments enhances the overall experience for a broader audience.
