General Information about Acadia (#181004)

The hex color #181004, commonly known as Acadia, is a very dark shade of brown. In the RGB color model, it is composed of 9.41% red, 6.27% green, and 1.57% blue. The CMYK representation is 0% cyan, 33.33% magenta, 83.33% yellow, and 90.59% black. This color leans heavily towards the darker end of the spectrum, and it is often associated with earth tones, natural elements, and a sense of grounding. Due to its low brightness, it can be challenging to use effectively in designs without careful consideration of contrast and readability. Its muted nature makes it versatile for creating a sense of warmth and sophistication, particularly when paired with lighter, contrasting shades.

The hex color #181004, also known as Acadia, presents significant accessibility challenges, especially in web design. Its extremely low luminance value makes it difficult to perceive, particularly for users with visual impairments. According to WCAG guidelines, using #181004 as text on a white background would result in a very poor contrast ratio, failing all levels of compliance (AA and AAA). Similarly, using it as a background color with white text would be equally problematic. To ensure accessibility, this color should be paired with very light colors to achieve sufficient contrast. For example, a light yellow or a pale cream color used as a foreground would improve readability. Avoid using this color for critical interactive elements or important information, as users may struggle to discern them. Furthermore, consider providing alternative visual cues, such as icons or descriptive labels, to reinforce the information conveyed by the color.
