Let's say that the Picklist is called "Risk" and the values are Green,Yellow,Red and Known Loss. We want to send an email out when the value changes from any value to another value.
Thanks!

This should work, converts your pick-list to text and won't fire if prior value blank (which it sounds like you only want changes between values)
(AND(not(text(Priorvalue(FIELDNAME )) = null),ISCHANGED( FIELDNAME)
