General Information about #101800

The hexadecimal color #101800, often referred to as Green Waterloo, is a very dark shade of green, almost appearing black. It is composed of 6.27% red, 9.41% green, and 0% blue. In the RGB color space, it is represented as RGB(16, 24, 0). The color's darkness is due to the low values across all three color channels, with blue being completely absent. This makes it lean heavily towards the green spectrum. The color is not commonly used in isolation due to its lack of brightness, but it can be effectively incorporated into color palettes that include lighter or brighter shades to create contrast and visual interest. When used appropriately, it can bring a sense of sophistication and depth to designs.

The hex color #101800, also known as Green Waterloo, presents significant accessibility challenges. Its low luminance value of 0.014 makes it difficult to read against both white and black backgrounds. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text. #101800 fails to meet these criteria with most background colors, posing readability issues for users, especially those with visual impairments. To improve accessibility, it is recommended to avoid using #101800 for text or interactive elements. If the color is essential to the design, consider using a lighter shade of green or pairing it with a very light background color to increase contrast. Proper contrast ensures that content is perceivable and usable for everyone, regardless of their visual abilities. Tools like contrast checkers can help evaluate and adjust color combinations to meet accessibility standards.
