General Information about #151205

The hexadecimal color code #151205, often referred to as "Green Waterloo," represents a very dark shade of green-brown. It is composed of 8.24% red, 7.06% green, and 1.96% blue. In the RGB color model, this translates to R:21, G:18, B:5. This color is characterized by its extremely low saturation and brightness, rendering it almost black. Due to its muted nature, it evokes feelings of earthiness, antiquity, or perhaps a sense of mystery. The color's spectral data indicates a dominant presence in the lower wavelengths, which aligns with its perceived darkness. In color theory, #151205 leans towards being an achromatic color because of the very small difference between the red, green and blue values.

The hex color #151205, also known as Green Waterloo, presents significant accessibility challenges. Its extremely low luminance of approximately 0.004 makes it difficult to perceive for individuals with normal vision, and especially problematic for those with low vision or color vision deficiencies. According to WCAG guidelines, this color fails all contrast ratio tests against white text. To ensure accessibility, it's crucial to avoid using #151205 for text or interactive elements without providing a very light background color that yields a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. In practical web design, using this color sparingly, perhaps as a subtle background accent or as part of a larger image where its legibility isn't critical, is advisable. Always prioritize sufficient contrast to meet accessibility standards and provide an inclusive user experience. Consider using color contrast tools to evaluate color pairings.
