You see a lot of Easter eggs
in Episode 4 of Star Trek: Lower Decks.
One of the things that you might not have noticed
is when Mariner is given her promotion,
she's also given a new uniform color.
Now, the uniform colors in Star Trek obviously apply
to the area of your expertise that you're working in
on the ship.
So you might question,
why does Mariner go from having a Command uniform
to sort of an Ops, yellow uniform?
And what we were trying to reference is,
in the early seasons of TNG,
when Geordi gets his promotion,
he also goes from having a red uniform
to having a yellow uniform.
Chief engineer.
It still has a nice ring to it.
Mariner does end up, at the end of the episode,
getting her regular uniform back,
but there's a lot of fun uniform stuff on Star Trek,
and it was just a little nod to Geordi's adventure in red.
