The Colour Out of Space

April brought a kind of madness to the country folk, and began that

disuse of the road past Nahum's which led to its ultimate abandonment.

It was the vegetation. All the orchard trees blossomed forth in

strange colours, and through the stony soil of the yard and adjacent

pasturage there sprang up a bizarre growth which only a botanist could

connect with the proper flora of the region. No sane wholesome colours

were anywhere to be seen except in the green grass and leafage; but

everywhere were those hectic and prismatic variants of some diseased,

underlying primary tone without a place among the' known tints of

earth. -- H. P. Lovecraft
