CSS Color: Green

Green in CSS is not the bright green most people expect — it is actually a dark, forest-like green at `#008000`. With zero red and blue, a green channel of 128, and only 25% lightness in HSL, it is significantly darker than Lime (`#00FF00`) which is what most people picture as "green."

In web design, Green is universally associated with success, confirmation, and positive actions. It is the standard color for success messages, checkmarks, online status indicators, and proceed buttons. This particular shade of CSS Green is dark enough for good contrast against white (approximately 5.1:1), making it usable for text.

From an accessibility standpoint, CSS Green passes WCAG AA for normal text and AA for large text against white backgrounds. This makes it one of the few saturated colors that can be used directly for colored text on light backgrounds.

Green pairs naturally with white, light gray, and cream. Red is its complement, so red-green combinations should be avoided for color-blind users (about 8% of males have red-green color vision deficiency). In Tailwind CSS, `green-700` provides a very close match.
