With the darkroom at your disposal and the set of filters, you can experiment with how light changes our perception of colors.

​

Take the black box with the small hole facing your face and the large hole facing upward.

​

Place one of the available colored filters above the large hole. Position a lit flashlight above the filter to illuminate the inside of the box. Now, place your eye against the smaller hole facing your face and observe the objects inside. Then, change the filter and observe again. What has changed?

​

Continue observing using all the filters and even combinations of multiple filters. Discuss with your peers what you have seen, also changing objects inside the room.
