#101500

General Information

The hexadecimal color code #101500, often referred to as Green Waterloo, represents a very dark shade of green. It is composed of 6.27% red, 8.24% green, and 0% blue. In the RGB color model, this translates to R:16, G:21, B:0. This color is significantly muted and leans heavily towards the green spectrum, with a noticeable absence of blue. Due to its low saturation and luminance, #101500 appears almost black. Colors like Green Waterloo are often associated with earth tones and can evoke feelings of nature, stability, or sophistication. However, its dark nature makes it less versatile for general use, particularly in areas where readability and contrast are crucial.

The color #101500, also known as Green Waterloo, presents significant accessibility challenges due to its low luminance. Its dark nature results in very low contrast against typical light backgrounds, such as white. This makes it difficult for users with visual impairments to perceive text or other elements rendered in this color. Web Content Accessibility Guidelines (WCAG) emphasize a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text against its background to meet Level AA compliance. Green Waterloo falls far short of these requirements, potentially excluding users with low vision or color blindness. To improve accessibility, consider using lighter text colors on #101500 or pairing it with much lighter background colors to ensure sufficient contrast. Providing alternative styling options, like a high-contrast mode, can also enhance usability for a wider audience. Avoid using this color for critical information without careful consideration of its impact on accessibility.
