One mother was kind enough to send me this photo: “My kids thought your book needed a little color”. I think this is a great surprise. I initially designed the books in the simplest way possible for children to illustrate. Unlike fine art, illustration needs to tell a story. So I felt black marker drawings would give the kids the best control, and I know from years of being a graphic designer that colors often turn to mud by the time they reach the final printing. So, I’m pleased to see that black & white books turned out even better than I imagined, because, to use modern vernacular, they are more interactive.
