Nope. If the bag looks blue that means it's scattering away blue light while letting the rest through. So it's filtering (out) the blue. OP is right.

- nostoc 6y agoNo, a blue filter, like a blue plastic bag would let blue pass and absorbe the other colors. That's why if you shine a white light through a blue filter, things look blue on the other side. Now, some of the blue light is scattered away, and that's why you see the plastic bag itself as blue.
- Nition 6y agoHang on, so if you shine a white light through a blue filter, the light on the other side looks blue. And the filter itself still looks blue on both sides. But then, where did the non-blue component of the light go?

- lgats 6y agoImagine looking at this blue-transparent bag with a red light, it will appear more opaque.
- ganzuul 6y agoJust like laser light protection goggles.
- natcombs 6y agoIf you see blue on BOTH the outside of the bag and the inside, what does that mean? I’ve never thought of this.
- nostoc 6y agoIt means some blue goes through, some is reflected.
