No, 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.

Hang 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?

Converted to heat. What's going on here is a discussion about transmission and transmittance. [1]

Imagine looking at this blue-transparent bag with a red light, it will appear more opaque.

Just like laser light protection goggles.
