General Information about Green Waterloo

The hex color code #121804, also known as Green Waterloo, is a very dark shade of green, almost appearing black to the untrained eye. In the RGB color model, it is composed of 7.06% red, 9.41% green, and 1.57% blue. This combination results in a subdued, earthy tone often associated with nature, stability, and a sense of groundedness. Due to its low lightness value, this color is more commonly used as an accent or background element rather than for primary text, as it requires careful consideration of contrast to ensure readability. The color is mostly used in darker themes or in combination with lighter, pastel colors.

The color #121804, also known as Green Waterloo, presents significant accessibility challenges due to its extremely low luminance. Its dark nature results in very poor contrast against typical light backgrounds like white, making it difficult for users with visual impairments to read text or distinguish elements. To ensure accessibility, it is crucial to avoid using this color for text or interactive elements without a very light background color that provides sufficient contrast, adhering to WCAG guidelines for contrast ratios. A contrast ratio of at least 4.5:1 for normal text and 3:1 for large text is recommended. Using tools to check color contrast is essential to verify compliance. If #121804 is necessary for branding or design, consider using it sparingly and ensure critical information is conveyed through alternative means, such as icons or labels with accessible color pairings. Always prioritize readability and usability by choosing color combinations that meet accessibility standards.
