According To Urban Legend, What Does The Red Dot On The 7up Logo Stand For?

A RED EYE. This comes from an urban legend about 7up inventor Charles Leiper Grigg, who was claimed to be an albino. There are no official references to Grigg having been an albino and in photographs his eyes look normally pigmented. The 7-up logo with the red dot came into use in the 1970s, long after Grigg had died. He created 7up in 1929 and died in 1940.
