Color Mixing Experiments for Teachers

Do you know the primary colors? They're red, yellow, and blue, right? Not always. The primary colors of light are red, green, and blue. When combined, they make white. The primary colors of printing ink are magenta, yellow, and cyan. When combined, they make black. Color Filter Paddles include primary and secondary colors, polarizing filters, and diffraction gratings. When the Mysterious Glowing Ball is spun in a circle by the cord, one can see the white light separate into blinking red, blue, and green lights.
