Members of the command division were trained in leadership and had tactical training allowing them to decisively take action in organizing and mobilizing Starfleet crews to perform missions. Command officers included most all of the admiralty, captains, executive officers, adjutants, and pilots (flight control officers, navigators, and helmsmen). (TOS: "The Cage"; Star Trek: The Original Series, Star Trek: The Next Generation, et al.)
Command division personnel also filled the posts of communications officer (TOS: "The Corbomite Maneuver", "Mudd's Women", "Miri", "The Conscience of the King"), records officer (TOS: "Court Martial"), phaser specialist (TOS: "Balance of Terror"), gunnery officer (TOS: "Arena"), radiation specialist (TOS: "The Galileo Seven"), TAC officer (TNG: "Coming of Age"), and strategic operations officer. (DS9: "The Way of the Warrior")
"In the old days, operations officers wore red, [and] command officers wore gold..."
In the Earth's Starfleet of the 2140s and 2150s, line officers of command division wore gold division stripes on their uniforms. (Star Trek: Enterprise) By 2233, command division personnel wore blue. (Star Trek)
Gold was again the color of the command division throughout the 2250s and 2260s, worn by line officers and flag officers of this division. Officers in the command division wore a five-pointed star with a lengthened upper point as an insignia on their assignment patch. (Star Trek: Discovery; Star Trek: The Original Series; Star Trek: The Animated Series; DS9: "Trials and Tribble-ations")
By the 2270s, new uniforms showed different division colors, the command division was signified by a white backing on their Starfleet badge, and also on uniform bands and epaulets. (Star Trek: The Motion Picture) This continued onto the 2280s uniforms, and the insignia used gave the officer the option of wearing command division white uniform insignia, with another department color banded across, or the opposite, with department color insignia with command white banded across. (Star Trek II: The Wrath of Khan – Star Trek Generations)
Individuals from several possible futures, and some that have been proven to be alternate timelines, continued to wear red when in the command division. (TNG: "Parallels", "All Good Things..."; DS9: "The Visitor"; VOY: "Endgame") By the 29th century, several timelines had switched the command color to blue. (VOY: "Future's End", "Future's End, Part II", "Relativity")

Command division officers
The Original Series
Once fully established during The Original Series, command gold was regularly worn by those in positions of higher authority, such as ship captains, commodores and admirals; however, evidence suggests that this was not a requirement for holding a command position. In the first case, starbase commodores Stone and Stocker both wore operations division uniforms, yet this exception seem to exclude commodore Mendez. The second case was that of Captain Krasnovsky, a starship captain who wore a sciences division uniform.
The helm and navigation officers typically belonged to the command division, as was the case in "The Cage", however, in "Where No Man Has Gone Before", the positions were held by operations officers, before returning primarily back to the command division once again.
Number One in "The Cage" and Spock in "Where No Man Has Gone Before" both served in the command division as first officer, before he switched back to the sciences division for the duration of the series (the same color he wore in the first pilot).
The work coveralls worn by technicians were originally muted variations on the division colors with the command division being represented by olive green, then later matching the duty uniforms. This coincides with the actual color of TOS which was lime green and only appeared gold under the lights.
The purpose of the colors was only obvious through inference, but in DS9: "Trials and Tribble-ations", gold was established in dialogue as the "old" style command color (and red as the "new" command color). The decision to switch the meaning of the colors between the TOS and TNG uniform styles was made in pre-production of "Encounter at Farpoint".

In the post-TMP movie era, several costume gaffes appeared. Saavik wore command white despite having a dual position as science specialist (as did Spock, but he was a captain at this point). The costume department had planned to give her uniform a science department color swatch also, but in an error, it was never seen on film. (citation needed • edit) Also, Scott jumped from command white to engineering gold after receiving his captain's bars (ironically, he effectively used them in the "wrong" scenarios, wearing gold with his formal duty tunic but white with the more casual bomber jacket and engineering vest).
During the course of The Next Generation, command level officers regularly wore red uniforms, however, again another exceptional case would appear in DS9: "The Die is Cast", where Admiral Toddman wore an operations uniform, the only such command level officer to do so.
Captain Braxton wore blue in VOY: "Future's End, Part II" and "Relativity", but an alternate version of him in ""Future's End"" wore red – indicating that Starfleet never changed the command color in that version.
