It belongs to the broader family of earth tones and is characterized by its low saturation and luminance. In the RGB color model, it consists of 9.41% red, 8.24% green, and 1.18% blue. Its CMYK representation is 0% cyan, 12.4% magenta, 87.4% yellow, and 90.59% black. Due to its darkness, Acadia is often perceived as a muted and grounding color. It evokes feelings of nature, stability, and understated elegance. The hex code #181503 is frequently employed in design projects that aim to create a sense of warmth, history, or connection to the earth, but accessibility is very limited.

The color #181503, also known as Acadia, presents significant accessibility challenges. Its very low luminance of 0.009 makes it extremely difficult to read text rendered in this color against a standard white background. According to WCAG guidelines, it fails all contrast ratio tests for normal text, large text, and graphical elements. To improve accessibility, it's crucial to pair Acadia with significantly lighter colors to achieve a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Consideration should be given to users with low vision or color blindness, who may struggle to distinguish this color even against moderately light backgrounds. For web applications, providing a color contrast checker tool or alternative high-contrast themes can greatly enhance the user experience for individuals with visual impairments.
