The best part of this book on mixing colors is the fact that it includes overhead transparencies.Yes, you heard me right, TRANSPARENCIES.The author uses different mixtures of blue, yellow, pink, white, and black to demonstrate how colors mix to create new colors.As an added bonus, Tison overlay colored animals on top of colored animals to create a third colored animal (blue seal + pink flamingo= purple turtle).OK maybe this is one of those books you have to see in person to understand.But I always thought it was magical as a kid.And informative.My husband, who is pretty much the smartest person I know, still asks me what primary colors make up secondary colors.And this is the perfect book to answer those questions.
