I am writing a story about colour for children. Can you help explain (in simple terms) how a rainbow works and how the mixing of just a few colours in printing pictures in papers works?
I like howstuffworks.com for reasonable explanations of many things. That link is for rainbows and I’m sure they have one on printers, too. As far as a simple explanation, I just like to say the different colors of light are bent to different angles by the raindrops in the air (for a rainbow). For color printing, you can say that we have only three types of color receptors in our eyes and the primary colors in a printer work to control the responses of those three receptor types. Since there are only three receptors types, only three primaries are required. <>br> Another good source is the “Magic Schoolbus” books on color and the senses.
