Lemon-lime Gatorade is chartreuse in color. The original lemon-lime Gatorade leaned more toward the yellow end of the spectrum, while newer versions lean more toward the green. The original lemon-lime Gatorade's hex code is #E4E21B, and its RGB code is 228 226 27.

Gatorade was the brainchild of four University of Florida researchers who were tasked with developing a beverage that would replace the carbohydrates and electrolytes that its athletes were losing when on the field in the hot Florida heat. Lemon-lime was the first flavor developed. The debate over whether it is yellow or green in color has been raging since the beverage made its debut.
