About Green Waterloo

#151203, also known as Green Waterloo, is a very dark shade of green, almost appearing black to the untrained eye. It is composed of 8.24% red, 7.06% green, and 1.18% blue. In the RGB color space, it has the numerical values of R:21, G:18, B:3. Its CMYK representation is C:0, M:0.14, Y:0.86, K:0.92. This color falls within the cool end of the spectrum, although its darkness mutes any vibrancy typically associated with greens. Due to its low saturation and high degree of black, it is often perceived as a neutral tone. This color is more appropriate for backgrounds or subtle design elements rather than being a primary focus.

The color #151203 presents significant accessibility challenges, primarily due to its very dark nature. With extremely low luminance, it offers minimal contrast against virtually any background, especially white or light-colored ones. This poses severe readability issues for users with visual impairments, including those with low vision or color blindness. Web Content Accessibility Guidelines (WCAG) emphasize a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. #151203 falls far short of these recommendations, making it unsuitable for text or interactive elements. To improve accessibility, consider using significantly lighter foreground colors or employing background colors that provide substantial contrast. Tools for checking color contrast ratios are readily available online and are essential for ensuring inclusive design. Avoid using this color for essential information without careful consideration of contrast.
