As the direct object of the verb, the list requires no special punctuation; I choose the last of the three.

Only use a colon when the introduction to the list can stand on its own as a sentence.
For example,
"Any list of colors has to include these: red, blue, yellow, green, orange and purple."
So,
"Any list of colors has to include these" is a complete thought.
But,
"Any list of colors has to include" is not a complete thought.
