Corn Snakes
Some breeds of corn snakes, which are found in the eastern U.S., are mostly yellow or have yellow markings. Butter corn and butter motley corn snakes, which are mostly deep yellow in color, are produced by uniting the genes of amelanistic and caramel corn snakes. Cremsicle corn snakes are often a distinct yellow to light orange color. Amber corn snakes turn a vivid yellow, similar to the shade of the butter corn snake, when they reach adulthood.
