Kelly Green

Kelly Green (Viper Green) is a vivid, warm solid green at #628351 — a medium, bright green with a slight yellow bias that distinguishes it from British Racing Green's deeper, cooler tone, reading as lively, sporty, and naturally botanical in direct light. Rennbow confirms that Kelly Green is interchangeable with Viper Green, with Kelly Green used in the US market while Viper Green was the rest-of-world designation — and that it was a popular colour in the 1970s first introduced with the famous 911 RS. Porsche Club of America commentary confirms that Viper Green / Kelly Green was one of the distinctive period green shades offered in the 1960s and 1970s, and that the popularity of green as a Porsche colour faded after the 1970s. One documented community example reflects both the colour's scarcity on surviving cars and the complexity of tracking it across the dual US/ROW naming convention, where a single car might carry either name depending on its market of sale and the documentation consulted.
