The original drink had an avocado green hue, made with a combination of yellow dye No. 5 and blue dye No. 1 artificial coloring, that honored the kiwi flavor in this particular Gatorade bottle ...

In the early days, it didn't exactly taste great - some athletes that drank it to replenish fluids even vomited from the flavor. Yum. Thank goodness Gatorade has upped their game and added flavor.
