[Star Wars] Is there any restrictions a Jedi has on the color lightstaber they have depending on their rank?

Lightsaber crystal colors mostly mean nothing. They especially mean nothing for "ranks."

A lightsaber's color is only meaningful insofar as when the user attunes to the crystal inside, it changes the color of the crystal - the most common colors are blue and green, but obviously those are not the only ones.

A dark side user gets their red crystals by forcing the crystal to bond with them, in essence the crystal is "bleeding" from this interaction.
