This color is often associated with urban landscapes, construction, and a sense of groundedness. Due to its dark nature, it is typically used sparingly in design and is often paired with lighter colors to create contrast and visual interest. This color is rarely used for fashion, because it is considered to be dull. It should be avoided in web design, unless used in combination with bright colors.

The hex color #170B0A, also known as Asphalt, presents significant accessibility challenges, primarily due to its very low luminance. This dark shade of brown demands careful consideration in web design to ensure readability and usability for all users, including those with visual impairments. When used as a background color, it necessitates very light text with a high contrast ratio to meet WCAG (Web Content Accessibility Guidelines) standards. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Using color alone to convey information is strongly discouraged. It is crucial to provide alternative visual cues, such as icons or text labels, to ensure information is accessible to colorblind users. Thorough testing with accessibility tools and feedback from users with disabilities is essential to validate the design's accessibility.
