You should do research on what corn you might want to get will look as an adult. I got a butter corn which is still a hatchling, and she has only a little yellow and that is on her head. When I look online I have found that butters can range from a bright yellow on the whole body, to only a little yellow on the head.

I also have a amelanistic corn that is my girlfriends snake. When we first got her they told us she was a hypo. We thought that she was really a candy cane. Do your research because you might think you are getting the snake you wanted, or like the look of as a baby. Then, you realize it's not what you thought it was. The good thing for us is that we didn't care. We just wanted to get our first snake, and after doing a lot of research on how to care for corn snakes we then just picked one that looked good at the moment.
