The answer to your question would be that 14 is correct because it does not require a comma. The sentence is a clear example of the use of cumulative adjectives. Cumulative adjectives don't separately modify the noun that follows even though they are stacked up before the noun. That fact is that the adjective before the noun pairs with the noun as a unit, and then the adjective before that unit modifies that.

Sentence 15 is correct because it does not require a comma either because of the same reason (the use of cumulative adjectives). As regards sentence 16, it can be said that it is incorrect because it does requiere a comma since the prepositional phrase "in Colonial America" is an introductory phrase.
