I had a small group of highlighter yellow dragons that I bred back at least 13 - 14 years ago, [ they didn't sell as well at the shows as the reds did because they took longer to color up ] and there were other breeders that had them before F + I existed. I would attribute some of the most spectacular yellows in the world to her collection though, but I had seen bright yellows before then and owned several.Teri was the one that came up with the idea of a pedigree with the parent dragon, the hatch date, etc., but she did get her yellows from other breeders. The high end yellows in this country came from Sandfire, some from Dragon's Den. Whether people believe it or not, most of the high color dragons in this country can be traced back to Bob Mailloux of Sandfire Dragon Ranch. Pete Weiss brought color in as well....these names may not be familiar to newer breeders but they are the real pioneers. At the shows back in the 90's, that was where most of the breeders got their colorful dragons, and I still have the Vivarium magazine featuring the bearded dragon special issue highlighting various color " morphs " [ the term in the article ] from 1996 [ volume 7, No.6 ] that listed the types of dragons in the trade then. There were no trans, no leathers [ if they were being bred then, they were still in the stage where they did not do well enough to be sold to the public ] and the sandfires were the hot dragons, bright reds + oranges that were distinct from the grey or tan " normals " at that time. German giants were mentioned as well , Pete Weiss being the one responsible for their popularity , as well as Kevin Dunne [ originator of one of the newest morphs today named after him the " Dunner " ]. Bearded dragon types, colors, morphs + descriptive terms will always confuse some people, but it's interesting to see the many changes that have taken place with breeding in the past 15 or so years.
