Normal Leopard Geckos
Normal Leopard Geckos or Wild Type Leopard Geckos are generally a dull yellow color with a large amount of black spots on them. The tail will be white with black spots on it. Before all of the colorful morphs came about, Normals and High Yellows were the only morphs available.
