The product's name came from the fact that the "dnL" logo is the "7 Up" logo turned upside down. The product itself was also, in many ways, the opposite of 7 Up: while 7 Up is caffeine-free, colorless, and comes in a green bottle, dnL contained caffeine and was an unusual shade of green (vaguely similar to the green of 7 Up's bottle) in a clear bottle. And while 7 Up has a fairly standard lemon-lime flavor, the "citrus" flavor of dnL is that of lime-lemon, (primarily lime flavored with a hint of lemon).
