This demo shows how color subtraction works in the world around us. The cyan, magenta, and yellow colors can be 'mixed' to produce any other color. When you see a certain color on a car, it is due to subtractive color mixing. If a car appears yellow, that is because the paint on the car is absorbing all colors EXCEPT the yellow wavelenght light which you will see as it gets reflected back at you. After putting the "paint" on the stage, you can drag the blobs around the screen to explore different color mixing.
