This state of things would have more credibility if they didn’t keep introducing blue dragons in every quest, book or patch.
There are unironically more named blue than red and greens.
Tyri, Haley, Senegos, Azuregos, Lanigosa, Jaracgos, Narygos, Kirygosa, Banagos, Teralygos, Alagosa, Awbee, Bezarus, Dagrona, Stellagosa, Kharmeera, Cyrrigos, Telagos…
…and perhaps more: Nymn (?), Zakk Sinon (?), Daleohm (?), Maseel (?) all of them are presumably blue dragons tossed out of Mazthoril.
Meanwhile DF introduced new NPCs:
Libergo, Doragosa (!), Lithragosa, Zelahosa and Hildegosa, Lynngosa, Oxigos, Saphiredos, Setogosa, Soragosa, Zuligosa, Alregosa, Coldostos, Conflago, Deragosa, Erugosa, Intinosa, Lynngosa, Kavigos, Tharkago
And perhaps more. This without counting the nameless NPCs such as Champion of Magic in the Dragon Soul, Visiting Dragon, the Azurewing drakes, etc; and small whelplings like Emmigosa or Saldigosa. There has to be enough of them to actually keep a small organization going.
