Chromatic dragon

Chromatic dragons are a type of dragon distinguished typically by a solid, non-reflective coloring of their scales as well, hence the name. Chromatic dragons are also very commonly evil.

Black dragons
Black dragons, or skull dragons, are the most vile-tempered and cruel of all chromatic dragons and possess an acid breath weapon. They make their lairs in large caves or underground chambers next to swamps or murky ponds. A black dragon's diet consists of fish, mollusks, aquatic critters and some red meat from terrestrial animals.

Blue dragons
Blue dragons are orderly creatures and are unusual for chromatics in that they keep fairly well-ordered, hierarchical societies. They are more likely to be mocking and manipulative than outrightly cruel or murderous to "lesser" creatures, aided greatly by their natural talents for hallucination. They are infamous for tricking desert travelers into drinking sand or going miles out of their way to avoid nonexistent dust basins. Its breath weapon is lightning or a large electrical charge.

Brown dragons
Brown dragons, also called great desert dragons, are wingless dragons with acid breath weapons. A brown dragon typically lairs in a large cave or underground chamber, deep under the desert sand.

Green dragons
Green dragons revel in combat, and will often attack for no apparent reason. They are highly territorial, and will often view any intrusion into their domain, voluntary or not, as a personal affront. They are extremely cunning and duplicitous foes, and love double-crossing others. A traveler who stumbles into a green dragon's territory might be able to bribe the dragon for safe passage, but more often than not the dragon will pretend to agree and then attack the unsuspecting offender once his or her guard is down. Their breath weapon is a cloud of green poisonous gas.

Red dragons
Red dragons are covetous, evil creatures, interested only in their own well-being, vanity and the extension of their treasure hoards. They are supremely confident of their own abilities and are prone to making snap decisions without any forethought. Red dragons are the most powerful of the chromatic dragons, and breathe a cone of fire.

White dragons
White dragons are the weakest and the most feral of the classic chromatic dragons, but they are by no means stupid or harmless. They are still powerful enough to overwhelm most humans and have exceptional long-term memories. Adult white dragons have several abilities well-suited to their arctic habitat: they can climb ice cliffs with ease, fly very high and fast, and are exceptional swimmers. They love to swim in cold water; the more frigid, the better. They breathe a cone of ice or frost.

Brown dragons
Ferocious, though intelligent beasts from the Forgotten Realms campaign setting which reside in the wastes of Eastern Mulhorand. They view humans as food and think it peculiar to talk with one's meal, but they talk to almost anything else. They have a membranous frill that connects each row of spines down the length of the dragon's body allowing undulating flight through the air.They also love digging in the sand.

Orange dragons
Crafty predators who attack from ambush. They prefer to lurk in deep rivers and lakes. They are highly territorial and natural tyrants who seek to bring creatures in their area under their control. They bear a passing resemblance to a monstrous, orange alligator.

Purple dragons
Long, lean bodied dragons with deep purple to midnight black scales. These fancy themselves to be the lords of all dragonkind, believing themselves arisen from the long dead sister of Tiamat. They are among the most intelligent of dragons, able to gather and control vast numbers of minions. Their energy-related attacks make them powerful fighters.

Yellow dragons
To clarify their breath weapon, it's a watery blast that contains a highly corrosive sodium compound. They adore water and often spend their free time playing in it.

Grey dragons
Grey dragons are the most rapacious, venal, and brutish of all the chromatics. Elder and ancient gray dragons have a special affinity with stone. They can exude a stony essence that petrifies foes that have been immobilized by their claw or breath weapon attack. An ancient gray dragon's spikes have an elemental resonance that petrifies not only the dragon's primary targets but also nearby creatures.
