It depends on what kind of filter it is. A blue light filter, will cause the image appear to be bluer, while a red light filter will make the image reddererrr... ^^
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.
A red filter.
The red light sails straight through the red filter unimpeded, and is then completely absorbed by the fabric. Since there's no green light floating around, there is no light at all to bounce off of the dress toward your eyes, and the dress appears black.
A red filter will absorb all but the red wavelength of light. A blue filter absorbs all but blue light. So the blue filter will absorb the red wavelength and no light will shine through.
the light becomes red :-P
it doesn't let light through

the whole spectrum turns red.
what happens when light enters a polorizing filter?
A red filter.
There are at least two different filters. First type is blocking red color and you see all color except red. Second type is blocking all colors but red. You see only red after light passed the filter.

the filter transmits red light and absorbs other colors.
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.
