In the RGB color model, it is close to black, indicating very low brightness. This color is frequently associated with earth tones, adding a sense of grounding and sophistication to designs. Because of its proximity to black, #170A0B is often used as a neutral background color or as an accent to darker palettes.

In terms of color theory, Asphalt can be described as a tertiary color, leaning toward the brown end of the spectrum.

The color #170A0B, a very dark, desaturated shade of brown, presents significant accessibility challenges. Its extremely low luminance makes it difficult to read text rendered in this color against almost any background, and vice versa. According to WCAG guidelines, it would fail most contrast ratio tests. For text to be legible and meet accessibility standards, it needs a contrast ratio of at least 4.5:1 against normal text and 3:1 against large text (14pt bold or 18pt regular). Given the darkness of #170A0B, pairing it with very light colors is essential. However, even with light colors, careful testing is needed to ensure readability for users with visual impairments. Designers should consider using lighter shades or different colors entirely to ensure that content is accessible to a wider audience. Testing with accessibility tools is strongly recommended.
