I'm going to give context to my adventure before I ask my question, if you would like to go straight to the question it will be marked with a series of dashes.
I'm cooking up an adventure where a rich businessman has the PCs go with his teenage son to a lazer tag-esque place modeled after the Tomb of Horrors, where two Dragonborn wizards create illusions for patrons who want to be adventurers but without any of the risk. The place is called TombZone, and it is modeled after the many lazer tag places that are near and dear to my childhood.
The businessman's son is hinted to be an accidental occurrence, with his face looking subtly longer than other children and having a very bad case of acne. Nevertheless, he's giddy at the opportunity to go on an adventurer with real heroes (which he badly hides under the facade of "being cool"). At certain moments during the adventure, such as when the party is being escorted to TombZone, the teenager will begin to groan in pain before being quickly attended to by an aide who soothes his pain. Perceptive players will notice that after each episode, his face grows a tiny bit longer and disfigured, and the acne becomes worse.
The PCs are ushered to TombZone, where they take off their armor and remove any dangerous items (the dragonborn wizards cast the illusion of armor, weapons, and magic onto the PCs and the teenager). The party then proceeds through an abridged and far less frustrating version of the Tomb of Horrors, where all of the death traps now only give a small setback and there are now signs telling the group exactly what they need to do.
The fun ends at the fake Acererak's throne room, where the businessman awaits and reveals himself to be the BBEG of the adventure. The DM can decide why the businessman is angry at the party (he's a minion for the campaign's antagonist, he has some score to settle with the party, etc.) He then summons the two dragonborn mages to kill the party when they're vulnerable (players can find a button that gives their items back to properly fight the wizards), and leaves his son to die, remarking that he's solving two of his biggest problems. The son begins to have another episode. With no aide to help him this time, his face and body fully contorts and alters to reveal a (maybe partial) transformation into a dragonborn. The businessman apparently had an affair with a dragonborn woman, with her giving birth to the son.
Now equipped with their items and with a very angry adolescent dragonfolk, the party attacks the wizards.
If a dragonborn uses its breath weapon against another dragonborn, does the dragonborn being targeted take damage (maybe with resistances?) I'm assuming this depends wildly based upon the color of both dragonborns.
Good lord, I've said the word dragonborn more times than should be humanly allowed.
Yes the target takes damage applying appropriate resistances and immunities, just like you hitting someone with a sword when they are wielding a sword.
I don't see why it should be any different than if they used their breath weapon against any other creature. Apply resistances as appropriate. E.g. if a gold DB used fire breath against a red DB, then the red DB will have resistance. A Brass DB attacked by a Blue DB with lightning breath will have no resistance.

Alright, thank you.
