Written in the first-person perspective of an unnamed surveyor from Boston, "The Color Out of Space" tells the story of the narrator's attempts to uncover the secrets behind a shunned place referred to by the locals of Arkham as the "blasted heath". Unable to garner any information from the townspeople, the protagonist seeks out an old and allegedly crazy man by the name of Ammi Pierce who relates his personal experiences with a farmer who used to live on the cursed property, Nahum Gardner. Pierce claims that the troubles began when a meteorite crashed into Gardner's lands in June 1882. The meteorite never cools, but begins shrinking and local scientists are unable to discern its origins. As the stone shrinks, it leaves behind globules of color that are referred to as such "only by analogy", as they do not fall within the range of anything known in the visible spectrum. These remains eventually disappear but, the following season, Gardner's crops come in unnaturally large and abundantly. When he discovers that, despite their appearance, they are inedible, he accuses the meteorite of having poisoned the soil. Over the following year, the problem begins spreading to the surrounding vegetation and local animals, warping them in unusual ways. The plant life around the farmhouse becomes "slightly luminous in the dark",[and Gardner's wife eventually goes mad, forcing him to lock her in the attic. During this time, Gardner begins to isolate his family from the rest of the town and Pierce slowly becomes his only contact with the outside world.
