Comma between coordinate adjectives

When two or more adjectives each modify a noun separately, they are coordinate.

Example sentence: Roberto is a warm, gentle, affectionate father.

Example sentence: The Gila Wilderness is a remote, wooded, arid tract of land.

Adjectives are coordinate if they can be joined with and (warm and gentle and affectionate).
