The crew of the Orville (and the Admiral) wear a wide range of uniform colours including red, orange, blue, green, blue, grey and purple.

Do we have a definitive indication of what these various uniform colours indicate?

    Blue is definitely reserved for primary command, I.e. Captain, 1st officer, and 2nd officer. Red is security. Green is medical. Orange.. So far is helmsman / navigation. The robot science officer doesn't wear a uniform, so we don't know what color he would get (maybe green). Grey... Janitors? Or maybe engineers. And i don't remember seeing purple. Oct 1 '17 at 15:20
  • @JackBNimble - The robot appears to have blue highlights.

    @JackBNimble - That's an awful lot of medical staff. Nearly 15-20%(ish) of the crew?

    Well, it is a sortof parody of StarTrek, and on that medics and science shared the same color. I would guess the same here. We wont know until we see more episodes I guess. Oct 1 '17 at 15:27

    @Morri - Sick bay, probably.

Purple: Admiralty

enter image description here enter image description hereenter image description here

We've seen three admirals, Tucker, Ozawa, and Halsey, and all three have purple uniforms, and they all sport the "Command" chest badge.

Blue: Command

enter image description here

We see this on Captain Mercer, Commander Kelly Grayson, and Lieutentant Commander Bortus. Again then have the Union icon that denotes command.

Green: Science

enter image description here

We see this on Doctor Claire Finn, she has the "science" badge.

Peter M and Datasaac have noted there is a non-medical science badge as well, though both show an atom diagram.

Orange: Engineering

enter image description here

Both helmsman and those in engineering wear this color and the "two gears" badge.

Red: Security

enter image description here

Lieutenant Alara Kitan wearing a red uniform with a "shield" badge.

Grey: Enlisted

enter image description here

Here we see the backs of several grey dressed crewmen. They appear to have colored stripes on their grey uniforms (green and red).

Here we see (albeit blurry) the grey uniformed crew have the same badges as officers denoting sections (engineering gears, science green, red shield security) with matching color stripes.

    Also, the clearly broad age range of the grey folk seems to rule out cadets (which they would be if it were a mapping to Trek), making enlisted the most likely choice.

  • Probably another question, but is there a reason Doctor Finn's green hair matches her uniform?

    Having just seen the 2018 Ja’loja episode, it features Jayne Tyler who is a Dark Matter Cartographer. Jayne sports the green uniform of a science officer, but has a totally different badge to Dr Finn. This indicates that there are divisions within each section, as speculated in the questions comments.

  • Good spot on the grey. However, it seems to make no sense. Colored uniforms are used to allow you to tell at a glance what people you need to pay attention too in a busy and noisy enviornment. So if the yellow guy is waving you know he's not waving to you, but if the red guy is waving... get down! Since enlisted outnumber officers, and they're the ones doing the work that you need to quickly ID, it would be more logical to reverse the color system. Jan 22 '19 at 16:43

    @MauryMarkowitz Very little about The Orville is logical. Jan 22 '19 at 17:03

The green science badge, different from the medical badge, although both share the schematic atom.

Character shown wearing green with the science badge


We have confirmation from the behind-the-scenes book, The World of the Orville, what the various uniform colours relate to;

Fleet uniforms are color-coded. Blue for command, green for medical and sciences, orange for helm, navigation and engineering, red for security.

It also notes that green is associated with a number of named specialisms;

Medical, Life Sciences, Astronomy, Chemistry, Biology, Exobiology, Mathematics and Computer Sciences

A uniform colour-guide was issued with the 2017 press kit to promote the show.

It's missing purple and grey, but this seems to be the first official confirmation of the uniform arrangements by the show's makers.

enter image description here

Command Level [Blue]
Those in the Command ranks oversee all aspects of the ship, with the primary goals of keeping its occupants - and those of the Planetary Union - safe.

Science Level [Green]
As an exploratory vessel, The Orville requires top-notch scientists to aid in its investigation of the unknown and help solve the riddles of the universe

Medical Bay [Green]
With space exploration comes the great unknown, and with it, the risk of injury or disease. Medical Officers aboard The Orville help keep the crew in tip-top shape.

Engineering Level [Orange]
It takes steady hands for the helmsman and navigator to steer through supernovas, black holes and asteroid fields - while the engineering officers and maintenance crew work at the speed of light in the heart of the ship.

Security Level [Red]
Intergalactic exploration doesn't come without making a few enemies. Security Officers protect The Orville against its intergalactic foes, such as the dreaded Krill.
