|No, Pernese dragons do not come in black. Nor do they come in purple, red, plaid or other colors not specified in the books. Due to Anne McCaffrey's rules for Fan Clubs, noone may have a white dragon. Jaxom's Ruth was a mutation..a sport and the ONLY one since he was also infertile
Green: female (20-26 meters). The smallest and most numerous of the dragons. Light, highly maneuverable and agile. Greens are sterile genetically due to the fact they were engineered that way in the days of the early colonists. It was believed at one time that firestone made them sterile, due to the fact that golds are fertile and don't chew firestone. In fact, the golds simply lack the ability to process the firestone into flame and only suffer stomach aches and vomiting if they chew it.
FEMALE ONLY / Male or female riders
Blue: male (24-31 meters). The workhorse of the dragons. Medium sized, the blues are as tough as the greens, but not as maneuverable.
MALE ONLY / Male or female riders, but male preferred (Fandom allowance/does not exist in books)
Brown: male (30-37 meters). Larger then greens and blues, some well grown browns are as big as the smaller bronzes and could actually mate with the queens if they so dared. They are more intelligent then blues and greens, with greater powers of concentration.
MALE ONLY / Male or female riders, but male preferred. (Fandom allowance/does not exist in books)
Bronze: male (35-40 meters). The leaders of the dragons. All bronzes compete to mate with the gold queens. Generally trained for leadership, bronzes and their riders are often WingLeaders and WingSeconds. The majority of Weyrleaders are bronzeriders, though sometimes a brownrider will surprise everyone by catching the Sr. gold at a Weyr.
MALE ONLY / Male riders only!
Gold: female (40-45 meters). The fertile females of dragonkind. Traditionally mated to any bronze who can catch her. Although browns can mate with queens - and sometimes do- this is unusual and not encouraged, though noone is going to stand in a determined male dragon's way if he choses to rise after a gold, regardless of his color.
FEMALE ONLY / Female riders only!
