Something quite strange is afoot at Colin's school. The new substitute principal, Mr. Greystone, has a million rules. He becomes so furious when students draw on his bulletin board that he bans colored art supplies, --which has an eerie effect on the once-vibrant school. But Colin's crayons don't want to stay put in the trash can, so they plan an escape. Will kaleidoscopic hues return to Hughes Elementary? This zany picture book will supply readers with plenty of laughs and a wealth of information about color theory.
