Yellow with one of their yellow paint balls
The Gungans, an amphibious species originating from the planet Naboo, cultivated a specific kind of natural paint ball. These naturally-derived spheres, containing pigments, were grown within the underwater city of Otoh Gunga. The performers of sling painting, notably the celebrated group called the Gungan Sling Brigade, utilized these paint balls. These items shared some resemblance in form with the boomas employed by the militiagungs within the Gungan Grand Army.
The natural paint balls of the Gungans debuted in the educational video game Star Wars: Early Learning Activity Center, released in 2000.
