Chromatic dragon is a classification of dragon found in the role playing game Dungeons & Dragons. In this setting, chromatic dragons are typically of evil alignment. They contrast to the metallic dragons, which are typically of good alignment.
Tiamat is the queen of chromatic dragons. Chromatic dragons have played a large role in various D&D monster compilation books: white, black, green, blue and red dragons being the classic chromatic dragons.
The classification of "chromatic dragons" was used in the Advanced Dungeons & Dragons second edition Monstrous Manual (1993), although the dragons comprising the category had been in print since the original Dungeons & Dragons "white box" set (1974). The term was continued in use in the third edition and fourth edition Monster Manual.
