Chromatic dragon

Chromatic dragons were a type of dragon distinguished typically by a solid, non-reflective coloring of their scales, hence the name. They were generally evil, greedy, and predatory, and usually worshiped Tiamat, whom they regarded as their queen.

It was believed by scholars from Candlekeep that all species of chromatic dragons evolved from the proto-dragon species of the inficedraco genus.

Some can even produce dragonic mules combinations of two colors(stated in 3e draconomicon).

Types
Although there were many chromatic dragon species, the following are the ones known by sages of Faerûn:


 * Red dragons: Red dragons were greedy, chaotic evil creatures, interested only in their own well-being, vanity, and the extension of their treasure hoards. They were supremely confident, being the largest and most powerful of the chromatic dragons. Typically found living in mountainous regions, they breathed a cone of fire.


 * Black dragons: Black dragons, or skull dragons, were the most vile-tempered and cruel of all chromatic dragons. Excellent swimmers who normally lived in swamps and marshes, they preferred ambush attacks. They had a corrosive acid breath weapon.


 * Blue dragons: Blue dragons, or storm dragons, were manipulative, lawful evil chromatics who were infamous for their skill at creating hallucinations, and their cruel use of such things. They preferred aerial combat, which allowed them to use their electrical breath weapon most efficiently. Blue dragons most often lived in arid wastelands and deserts. They were the second most powerful of the chromatic dragons.


 * Green dragons: Green dragons were highly territorial, deceptive, forest-dwelling creatures who loved secrets and intrigue. Although lawful evil, they were duplicitous and cunning foes who loved combat. They were the third most powerful of the chromatic dragons. Their breath weapon was a cone of poisonous green gas.


 * White dragons: White dragons, also called ice dragons or glacial wyrms, were the smallest and weakest of the classic chromatic dragons. However, they were by no means harmless. White dragons were extremely well-suited to their arctic habitat and had excellent memories. They were more feral than other dragons, though, and always chaotic evil. They breathed a cone of ice or frost.


 * Brown dragons: Brown dragons, also called great desert dragons, were wingless, neutral evil dragons who laired in deserts. They preferred ambushes to straightforward combat, burying themselves in the sand.


 * Purple dragons: Purple dragons, also called deep dragons, were slender, agile dragons who patiently stalked their prey. They lived in the Underdark and were rarely found on the surface. Purple dragons often allied with drow, and considered themselves rivals of cloakers and mind flayers. They were chaotic evil and had a psychic "breath weapon" that confused and disoriented the target.


 * Gray dragons: Gray dragons, also called fang dragons, were rapacious, violent dragons that were good at physical combat but poor at flying. Some gray dragons possessed an acid breath weapon.


 * Yellow dragons: A very rare species of chromatic dragons, only a few individuals of this species had been spotted throughout history. Yellow dragons were solitary predators and secretive creatures, even among dragons.
