Miami phase is a term used to describe the look of a snake. It is not really a simple yes or no, on or off type answer. Miami phase snakes are different from normal corns (which they really are a normal) because they have a gray, sometimes tan background, I'd say your qualifies as a Miami phase. There can be a fine line between what one person calls a Miami phase and what someone else does. Some have a more critical eye and if it's not near the perfect description then it's not a Mami phase.
