Due to its low luminance and saturation, it is often associated with feelings of darkness, calmness, and subtlety. In design, it should be used cautiously, especially for text, because of its low contrast against light backgrounds. It might be more appropriate as a background color or as an accent color when paired with much lighter shades to maintain readability and visual interest.

The color #121506, a deep, muted green, presents significant accessibility challenges. Its low luminance value of approximately 1% means that text rendered in this color against a standard white background will have extremely poor contrast. According to WCAG guidelines, the contrast ratio would be far below the minimum requirement of 4.5:1 for normal text and 3:1 for large text. This makes it difficult for users, especially those with visual impairments, to read the content. To improve accessibility, consider using a much lighter color for the text or a lighter shade of green for the background. Alternatively, implementing a color contrast checker during the design process will help ensure sufficient contrast for readability. Avoid using this color for critical information or interactive elements without careful consideration of the contrast.
