That is the experiment. All the boxes are the same color except for one (the oddball), which the subject is supposed to identify. The original study claimed that the Himba were (slightly?) faster to pick the oddball when it was a slightly different shade of green than UK English speakers. When the oddball was blue, UK English speakers were faster than the Himba.
