This was one of my favorites as a kid. As a budding young artist I was really excited by the colors in this book. And it teaches you how to mix colors!
ROSES ARE READ. ARE VIOLETS BLUE?
BY ALICE AND MARTIN PROVENSEN
A RANDOM HOUSE PAPERBACK
Copyright 1973 (this was before I was born so it must have had a long print run - maybe they'll bring it back!)
I loved this car crash scene at the end. If you put too many colors together you get mud! So true, so true.
