The goal of the series of experiments is to allow students to learn how different colors of light can interact and mix to produce various new colors. The experiment utilizes 3 different color LEDs (red, green, and blue) to produce a wide range of colors.
Many of the current video displays, such as a computer monitor or TV, uses the concept of additive color, where three different colors of light are combined in order to produce a wide range of colors. The primary colors often used are red, green, and blue. Through different combinations and proportions, it is possible to cover the entire visible spectrum. For example, equal parts of red and green, green and blue, and red and blue produce yellow, cyan, and magenta, respectively. These generated colors are known as additive secondary colors. Combining all three primary colors creates white light.
