As an assistant to a notable painter, your task is to create the required colors by mixing the given colors, and you need to do so by using additive or subtractive methods. The former method involves the mixing of light in which the colors are added up, for example, when red light and green light combine, the yellow light is produced. The other method involves the mixing of paints in which some colors are selectively removed, for example, when yellow paint is mixed with cyan paint, the green paint is formed. In each question you will be shown a color, and you need to click the corresponding primary colors, then click the OK button that appears on the right of the screen.
