+1 on what ElSass said.
Amelanistics are without black pigment, leaving behind oranges, pinks, reds, and whites. Amels have been line bred for many years and many generations now to create a WIDE variety of coloration within the "red-pink" spectrum. Some are mostly a deep red, others are as pink as a valentine's day card.
I'm very partial to amel corns, as my first snake was an amel corn.
There are dozens of corn morphs (including combo morphs) you can find for under $50. Because they're so numerous, I'd suggest hitting up a show sometime and being able to see a number of them in person.
