The Big Orange Splot is a children's picture book by Daniel Manus Pinkwater.

Mr. Plumbean lives on an orderly but mundane street, where all the houses look the same.

Instead he decorates his house with a psychedelic tropical theme.

After spending an evening with Mr. Plumbean, the neighbor also remodels his house to look like a ship.

Gradually the other neighbors find themselves following suit, each one spending an evening with Mr. Plumbean, and then going on to remodel their own homes to resemble their dreams.
