Olfactive expert Dawn Goldworm believes that just as children begin to learn colors, they should also be educated on scents—and make meaningful, emotional connections between the two. Goldworm has synesthesia, a condition in which normally separate senses mingle together involuntarily; sounds may conjure vivid colors, or touch may trigger a distinct taste. Spending her career putting her rare abilities to use, developing fragrances for such international brands and celebrities as Valentino, Harrods, and Lady Gaga, she has now brought her interest in sensory education to life in the form of The Smell of a Rainbow (Dial Books), a scented board book, out this summer, that teaches children how to talk about smell using color. Connecting all her research to date and providing tools for kids to better understand and articulate their emotions, the book features seven evocative fragrances that relate to the stripes of the rainbow.
