Answer 1

If 1000 people are pointing two flashlights in two directions in a V shape like this V V V V V V V, you can’t see both sets of lights unless you stand really far away.

Certain colors are only viewable from certain angles. All the red light comes out of all the droplets in one direction. All the blue light in another.
