Nothing comes through. A red light emits no blue light, and a blue filter allows
only blue light to pass ... that's why when you look at it, you say to yourself
"Hey! That filter looks blue. I'll call it a 'blue filter'."
red because red through red makes red! ;)
The red light is absorbed by the green filter and therefore no light passes through the filter
After pure, white light passes through a red filter, all the other colors in the spectrum will flow out of the other side. My mistake, I had a faulty source. A red light filter will cause the image to appear as different shades of red. Since it is a red filter only red light can pass through. So you finish up with red light. Whether it is focussed to an image or not is of no consequence. As to different shades of red, you will get the shade of red that is passed by the filter.
Red or blue. The reason a red filter looks and is red, is because only red light comes through it, and the same can be said about a blue filter allowing only blue light through. Other colors are absorbed by the dyes in the filter. If white light enters a red filter, then red light comes out, and the same goes for blue.
It depends on what kind of filter, e.g. a blue filter absorbs everything except blue light, so only blue light comes out, which is why the filter looks blue, and is referred to as a "blue filter".

The first load of water that passes through an activated carbon filter may contain some carbon dust (which will give it a tint of black). You are normally advised to flush the filter through once or twice and discard these first flushings. You will find that after this the water comes through clear. I am sure the carbon will not harm you but just to be safe discard the tinted water.
All other components of the white light, except magenta, are absorbed by the dyes in the filter, and only the magenta light comes out the other side. That's why the filter appears magenta when you look at it, and that's why the manufacturer cleverly named it a "Magenta Filter".
White light contains all colors. When white light passes through red glass, for example (or any red thing that passes light through it), all of the colors except red are removed (filtered out) so the resulting light only contains the color red. This is a big part of the reason why that piece of glass comes to be called "red" glass.
it comes out the other end
it melts, and then comes to land as rain.

The technique is filtration, and the liquid which comes through is the filtrate.

smoke comes through the filter on the cigarette and into your lungs
it comes out pink plus green
