In the RGB color space, it closely leans to a near black hue. This color exhibits a low saturation and luminance, contributing to its muted and earthy appearance. Colors like this are rarely used in mainstream designs, but can provide a grounded accent for applications that warrant it. The color is best suited for designs that demand a sense of earthiness, military or industrial applications.

The color #151809, also known as Green Waterloo, presents significant accessibility challenges. Its low luminance value of 0.014 makes it extremely difficult to read text rendered in this color against a standard white background. According to WCAG guidelines, this color fails all levels of contrast compliance (AA, AAA). To ensure readability and accessibility, it is strongly advised against using #151809 for text or interactive elements without implementing substantial contrast enhancements. A lighter color should be chosen for the foreground if #151809 is used as the background. A contrast ratio of at least 4.5:1 is recommended for normal-sized text and 3:1 for large text (14pt bold or 18pt regular) to meet WCAG AA standards. For AAA compliance, these ratios increase to 7:1 and 4.5:1, respectively. Employing tools that assess color contrast ratios is crucial for web developers to avoid accessibility issues and ensure inclusivity for all users, including those with visual impairments.
