Was there a soft drink called rainbow sprite?

Sprite is a popular lemon-lime soda, but it's never been sold in a rainbow version.

It's possible you might be thinking of:

* Sprite Remix: A limited-edition Sprite flavor that came in various colors and flavors, but not necessarily a rainbow.

* A local or regional brand: Some smaller companies might have created their own "rainbow" versions of Sprite-like drinks.

* A fan-made concept: People online might have created artwork or memes featuring a "Rainbow Sprite" concept.

If you can provide more context, like where you heard about this drink or what it was supposed to be like, I might be able to help you find more information.
