Let’s make the primary colors by using three flashlights.

Three colors of cellophanes (red, green and blue) are required to change the colors of lights.

Affix these color cellophanes to the flashlights as shown in the photo.

You can make the red, green and blue lights.

The primary colors can be combined to make various colors.

Let’s enjoy the combination as follows.

Red + Green = Yellow

Green + Blue = Cyan

Red + Blue = Magenta

Red + Green + Blue = White

Note the combination of the primary colors (Red + Green + Blue) is NOT black.

Hope you and your kids enjoy the exam.
