Concept books – in this case, books about colors – are not all that simple to write and sell. That was the lesson I learned recently after I had a GREAT IDEA for a picture book about colors, and it has gone nowhere! I share some research on COLOR books, but it applies to any concept.
A concept book’s primary purpose is to introduce/reinforce a specific area of learning. Colors, numbers, ABC, opposites, pets, and on and on, in board book format for ages 0-3. As I looked at comp titles, however, I found distinct types of books featuring colors.
Concept
This is the very simplest kind of book. There are fewer than 10 words per page, clear photos or pictures, often on a white background. They are written by an author/illustrator, or the text is compiled by publishing staff, or they are work-for-hire projects.

Here We Are: Book of Colors by Oliver Jeffers
Colors by Shelley Rotner
Hello Hello Colors by Brendan Wenzel
Simple Storyline
Teaching colors is still the central goal of the book, but the entire book is less than 5 sentences that tie the colors together in some way. They can be read to ages 1-4, even in group Storytimes, and are often perennial best sellers. Often, the background is still white, but the images may be more detailed.

Complete Story
In these books, color learning is not at the center of the story but is used to enhance it. These books are best for kids who know the basic colors, about ages 3-6. The pictures are more elaborate with backgrounds and action by the characters. The author is often the illustrator.

Continuing Series
These books are one of many concept books in a series featuring the same characters or theme. They are often developed by publishing staff or assigned by work-for-hire authors.

Older Kids
Ages 4-9 have picture books about colors, too, with more complicated plots. They are good for Storytime or reading with kids rather than on their own since the vocabulary is not limited.

I did figure out why MY book was not selling – I wrote one with a unique twist on colors, but as a board book, I was told it would be written by the staff. Sigh.
This month, choose a simple concept and see how it might be developed for different levels. Which one is your book to write?
