General Information about #151400

The hex color code #151400, sometimes referred to as 'Green Waterloo', is a very dark shade of green. It is composed of 8.24% red, 7.84% green, and 0% blue. In the RGB color model, this translates to R:21, G:20, B:0. The CMYK representation is C:0, M:0.05, Y:1, K:0.92, indicating a high level of black. This color evokes a sense of earthiness and can be associated with nature and stability. However, due to its low luminance, it is not a very versatile color and needs to be used carefully, especially in designs that require good readability and accessibility. It is very close to black.

The hex color #151400 presents significant accessibility challenges, primarily due to its very low luminance. The contrast ratio against a standard white background ( #FFFFFF) is extremely poor, making it difficult for individuals with visual impairments, including those with low vision or color blindness, to discern text or elements using this color. Therefore, it's crucial to avoid using #151400 for text or important interface elements without implementing substantial contrast enhancements. To improve accessibility, consider using significantly lighter shades of green or yellow for the foreground if #151400 is used as a background, or vice versa. Adhering to WCAG (Web Content Accessibility Guidelines) contrast ratio requirements is essential to ensure that content is accessible to a wider audience. Tools are available online to check color contrast ratios and suggest accessible color combinations.
