From Leopard Gecko Wiki
The Nieves Tangerine geckos were pioneered by David Nieves in the mid 90's. The Nieves Tangerines are Line Bred Tangerines geckos that have a distinct look. These geckos have Tangerine coloring, but their spots seem to be larger than other Tangerines.
Currently it is very hard to find Nieves Tangerines which have not been crossed into other bloodlines. As of right now, Paul Allen from Bright Albino is working with them.
