Field Trip

I was very tempted to send you on a trip to England to experience firsthand the real-life crop circle phenomenon up close; some of the more publicized crop circles have been in England, although crop circles have actually appeared all over the world. Because a trip to England might not be convenient for you, let's instead take a field trip to learn more about primary colors and how they are used in varying combinations to form other colors. More specifically, I want you to visit your local toy store and buy some Play-Doh or other suitable colored clay. Experiment with creating different colors by combining primary colors of Play-Doh, which in this case, will likely be red, blue, and yellow, as opposed to the red, green, and blue colors used in RGB computer graphics. As you squish together different colors, keep in mind that Play-Doh color combinations are subtractive, which means that mixed colors are subtracted from each other to become black; in other words, the more colors you mix, the darker the result. Computer graphics are additive and therefore have the opposite effect when combined; they get lighter as you combine them.
