The color of an object was its property of producing different sensations on the eye as a result of the way it reflected light. The planet of Felucia hosted many translucent life-forms that colored the sunlight as its beams penetrated their skin. Blue, green, red, and yellow are examples of colors.
Ahsoka Tano's lightsabers were white, due to her purifying a pair of red kyber crystals that were "bled."
The color of a Jedi lightsaber's blade was defined by its kyber crystal, which was harvested from the Crystal Cave on Ilum. A lightsaber crystal was colorless until it was found by a Jedi youngling, where the youngling would then become attuned to the crystal and the crystal would display its color. The color being determined by the youngling's "spiritual alignment." A Jedi's lightsaber blade was usually green or blue, but other colors were possible, such as Mace Windu's purple-bladed lightsaber. The Sith often wielded red lightsabers due to a process known as bleeding, where the user used the dark side of the Force to bend a kyber crystal to their will. Additionally Jedi can use the Force to heal them of the dark side presence, causing them to turn white.
Specialized B1-series battle droids were distinguished by colored markings on their armor. Blue denoted pilot droids, red denoted security droids, and yellow denoted command droids.
Sheev Palpatine, Supreme Chancellor of the Galactic Republic, favored the color red.
In the galaxy, colors were often culturally significant. For example, the color red was associated with diplomatic immunity under the Galactic Republic, warning others not to attack. As the color of ambassadorial relations and neutrality under the Republic, a completely red color scheme such as that of the Consular-class space cruiser Radiant VII indicated a ship came from the capital world of Coruscant. As the personal favorite color of Supreme Chancellor Sheev Palpatine, red was co-opted during his chancellery and assigned across Republic vessels at his direction. Dark red was also the main color scheme on Republic ships and vehicles during the Clone Wars, whereas the Separatist ships and vehicles largely used dark blue. However, the color red was sometimes regarded as intense and aggressive. For that reason, the Sith wielded red lightsaber blades that represented their destructive view of the Force. Nevertheless, the members of many Force-worshipping sects native to Jedha donned scarlet vestments.
Clone troopers often painted their armor in accordance with the unit to which they were assigned.
Likewise, the white color of clone trooper armor signified an honorable symbol of defense before becoming skewed into one of a faceless icon of conformity under the Galactic Empire. During the Clone Wars, the clone troopers were referred to as "the boys in white." In the days of the Old Republic, silver was used as a status symbol for royalty, as residents of Naboo used chromium to cover their starfighters and cruisers.
All languages combined, there existed forty billion, eleven million, seven hundred forty-two thousand, nine hundred and eighty-three accepted synonyms for the color blue. In Galactic Basic Standard, known shades of blue included ao, aqua, azure, and royal blue.
The Galactic Empire favored muted colors of gray, white and black and tried to redesign ships, uniforms, and other government property in this color scheme wherever possible. Sabine Wren was not in favor of this practice and used graffiti to provide bursts of brighter color. In the Imperial Military, the wearing of white tunics was generally reserved for either Grand Admirals or members of the Imperial Security Bureau. Imperial armor was often black, as seen on people like Darth Vader, TIE pilots, members of the Inquisitorius and Moff Gideon.
The flight suits worn by the starfighter pilots of the Resistance were dyed in a hue known as "interstellar orange." Each group was also designated by various hues, such as Red, Green, and Blue Squadrons, along with their leaders.
Podracers were painted in various colors.
On Tatooine, where the sport of podracing was common, racers wielded various colors on both their vehicles and flags.
In Tarisian culture, the color purple was considered the "color of administration."
Caf without any cream or sugar added was referred to as "black"; Jedi Master Obi-Wan Kenobi was known to prefer black caf. One form of caf was described as "black and sweet".
When it came to clothing, individuals had different preferences when it came to color. For example, when Luke Skywalker put on an Imperial officer's uniform while on a mission to Coruscant, one of his fellow rebels commented that he looked good in black. After this, Skywalker began wearing black clothing.
A human parent could pass on their eye color to their offspring. Ben Solo had the same piercing brown eyes as his mother Leia Organa, who was sure that this feature was inherited from her own birth mother, Padmé Amidala.
Traditionally, the color of the armor on a clone trooper denoted ranks such as sergeants and lieutenants. However, this practice was rescinded as the war progressed, instead being used to signify belonging to a certain division or unit.
Luke Skywalker's black outfit in the 1983 film was deliberately designed to make him look similar to Darth Vader.
