General Information about #121901

The hexadecimal color code #121901 represents a very dark shade of green, often referred to as 'Green Waterloo.' It is composed of 7.06% red, 9.8% green, and 0.39% blue. This color is most frequently perceived as a dark, muted green. Colors with hexadecimal values are commonly used in digital design and web development. In the RGB (red, green, blue) color model, this color is created by combining a small amount of red and green with almost no blue, resulting in its distinct dark, earthy tone. It closely resembles shades found in natural, dimly lit environments. Due to its low brightness and saturation, Green Waterloo creates a calming and subdued atmosphere.

The hex color #121901, also known as Green Waterloo, presents significant accessibility challenges. Its low luminance value of 0.011 makes it a very dark color, providing insufficient contrast against white text or backgrounds. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. This color would likely fail these criteria when paired with standard light text. To improve accessibility, consider using lighter shades of green or complementary colors like yellows or oranges to ensure readable text. Using color alone to convey information is discouraged; supplement with text labels or icons for users with visual impairments. Always test color combinations with accessibility tools to verify compliance with accessibility standards.
