What is the name of a Children's Book...?

In the 60's or 70's there was a children's book that told a story of Mr. Green (I think) who lived in a row house. All of the houses were identical. Mr. Green wanted his house to be different. One day he painted his row house purple, if I remember correctly. It stood out from all of the other houses. The next day, all of the neighbors had painted their houses purple.





Any help would be greatly appreciated.

"Mr Pine's Purple House" by Leonard Kessler?


"Mr. Pine lived on Vine Street in a little white house." That's all fine and dandy, but there are 50 white houses on Vine Street, all in a line, and Mr. Pine can't tell which one is his! To distinguish his own abode, he decides to plant a little pine tree in front, but his neighbors like that idea so much, they do it, too. Even when he plants a bush next to his tree, everyone follows suit. Finally, Mr. Pine paints his house purple--and to his delight, no one else wants a purple house. His neighbors are inspired, however, to paint their own houses all different colors, their first break with conformity. ("'Yellow for me,' said Mrs. Green. 'Green for me,' said Mrs. Brown.")
