General Information about #001B11 (Holly)

The hexadecimal color code #001B11, also known as Holly, represents a very dark shade of green. It is composed of 0% red, 10.6% green, and 6.7% blue. In the RGB color model, it's defined by the values (0, 27, 17). The color is often associated with nature, calmness, and sophistication, but its darkness requires careful application to avoid visual monotony or accessibility issues. This color is more prevalent in designs that aim for a subdued or earthy aesthetic, where subtlety and understated elegance are desired. It is part of a spectrum of dark green colors that can be used to create a deep and rich visual experience, but due to its low luminance, it's essential to consider contrast and readability when used in combination with other colors.

The color #001B11, also known as Holly, presents significant accessibility challenges, particularly for users with visual impairments. Its extremely low luminance value of just 2.9 cd/m² falls far short of the WCAG guidelines for contrast ratios. When used as text against a white background, the contrast ratio is approximately 7.2:1, failing the AA level requirement of 4.5:1. Against a black background, the contrast ratio is negligibly better. This means that text rendered in #001B11 may be difficult or impossible for some users to read. To improve accessibility, consider using lighter color variations or pairing it with brighter complementary colors. It is crucial to test color combinations using accessibility evaluation tools to ensure sufficient contrast for all users. Remember to consider users with color blindness by checking how color contrasts appear using simulators for various types of color vision deficiency. Also, avoid using color as the sole means of conveying important information.
