"Richard Snider's Additions" in JG 37 "The First Fantasy Campaign" provide detailed statistics for six types of dragons, and I can't help but wonder if this might have been the source used for dragons in OD&D vol. 2 "Monsters & Treasure".
Gary Gygax had previously published descriptions of white, black, green, blue, and "mottled" dragons in the "Diplomacy" fanzine Thangorodrim (see OD&D Dragons: On the Origin of Species). (Mottled dragons were another name for purple worms).
The entry for dragons in Chainmail includes a description of "the Great Red Dragon (Draco Conflagratio, or Draco Horribilis) which is typified in Tolkien's The Hobbit", and lists the other colored types, except for gold dragons.

As all in the village are now aware, thanks to the massive appetites of the little ones, the Wizard's pet Dragon, affectionately called Gertrude, has been reliably reported to have given birth (Hatched?) five offspring of various sizes, shapes, and colors. The young Dragons have been busy learning to fly and hunt with sharp increases reported in the cattle herds of the vicinity.
