It is a gift and I’d make someone VERY happy.  All I could get from her is that the book probably from 1970’s, maybe earlier. The main character was a boy with a dog, there was also a girl in book that a cat. Book went from colorless to having colors (or maybe dull to colorful) as more colors appeared, the boy became more happy. Flowers became colorful, each petal would have different fabric in different colors.  Other items changed colors too and they were all patchwork-looking.  

I know this isn’t a ton to go from, but it is a unique-sounding book, so my fingers are crossed.  Many thanks, you may be my new hero if you can assist.  

Captain Kangaroo takes zoo’s animals home to their habitats.  In an airplane, they travel, slowly dropping different animals off: camels, brown bear.  Penguins are last, and say “Too hot! Too hot!” when in the Sahara, etc.  World map at the end showing their travels.  Orig bought in Chicago.

I got this book from the picture-book section of the library in the 1990s, I think. It was quite new then. It is about someone who wants to make an angel cake as good as her mother’s (grandmother’s?) but she doesn’t know the secret ingredient. Some angels come and make the cake for her, I think. Maybe they eat it too? I am not too clear on the plot, but I thought the illustrations were BEAUTIFUL! The angels are obviously portraits of real people. Obviously, someone else loved this book too because it disappeared, and I could never find it again. The author’s name was at the end of the alphabet- I only remember that because of where the book was on the shelves.
