Now that we're on our third subquestion, "How can light have different colors?" we're thinking about how we can manipulate light to have an effect.
Using different colored filters and flashlights, we saw three big ideas:
1. Using MORE light results in a brighter color.
2. Using a colored filter over a flashlight changes the color of light we see.
3. Combining red, green, and blue light makes white light!
And while this didn't really make sense at first, it now does. Any time there's more light involved, there's more light that can scatter back to the eyes. Even if green, red, and blue are darker colored lights, combining them together makes MORE light, and when there's more light, there's a brighter color!
