Dragonborn with chromatic ancestry claim the raw elemental power of chromatic dragons. The vibrant colors of black, blue, green, red, and white dragons gleam in those dragonborn's scaled skin and in the deadly energy of their breath weapons. Theirs is the raw elemental fury of the volcano, of biting arctic winds, and of raging lightning storms, as well as the subtle whisper of swamp and forest, toxic and corrosive.

Breath Weapon
When you take the Attack action on your turn, you can replace one of your attacks with an exhalation of magical energy in a 30-foot line that is 5 feet wide. Each creature in that area must make a Dexterity saving throw (DC = 8 + your Constitution modifier + your proficiency bonus). On a failed save, the creature takes 1d10 damage of the type associated with your Chromatic Ancestry. On a successful save, it takes half as much damage. This damage increases by 1d10 when you reach 5th level (2d10), 11th level (3d10), and 17th level (4d10).
You can use your Breath Weapon a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest.
Draconic Resistance
You have resistance to the damage type associated with your Chromatic Ancestry.
Chromatic Warding
Starting at 5th level, as an action, you can channel your draconic energy to protect yourself. For 1 minute, you become immune to the damage type associated with your Chromatic Ancestry. Once you use this trait, you can't do so again until you finish a long rest.
Languages
You can speak, read, and write Common and one other language that you and your DM agree is appropriate for your character.
