Murphy Patternless
Pat Murphy produced the first Murphy Patternless in 1991. This morph is solid grey/silver with light yellow markings and lacks all black and yellow patterns generally associated with leopard geckos.
As hatchlings they have light tan, yellow, and grey colored mottled speckles and splotches on their bodies, but this goes away as they reach adulthood. As Murphy Patternless mature, they will develop a slight yellow coloration to their body. Some have even been line bred by breeders such as Golden Gate Geckos to exhibit Carrot Tail traits.
